2. Compliment / Complement

These two words are pronounced the same, but they are spelled differently and have different meanings.
Compliment can be both a noun and a verb. A compliment is a positive comment about someone or something, for example: "You have beautiful eyes!"
And the verb compliment (or the expression "pay someone a compliment") means to make a positive comment:

(b) He paid me a compliment on my web design skills.
The adjective complimentary means "free":
(c) At this hotel, breakfast is complimentary.

Complement can also be a noun or a verb. If two things complement each other, it means they go well together; they make each other appear better.

(f) My business partner and I really complement each other.
The adjective complementary means that two things are different, but go together well.

3. Discreet / Discrete 

These words are pronounced the same, and they are both adjectives.
Discrete means separate, distinct, individual:
(a) The two companies have a partnership, but they are discrete entities.
Discreet describes something that is modest and does not call attention to itself:

When you describe a person as discreet, it means that person can handle sensitive topics with tact (good manners and professionalism).

4. Enquire / Inquire 

Both of these verbs are used for asking about something or looking for information.
The nouns for the request / investigation are enquiry and inquiry.
Technically, enquire is used for “ask” in general (“He enquired about prices for the products”), and inquire for a more formal investigation (“The police will make an inquiry into the alleged corruption.”)

5. Especially / Specially 

Use especially when something stands out from all the others (similar to the meaning of "particularly.")

10. Such as / As such

Such as means “like” or “for example”:
(a) There are lots of things to see in New York City, such as the Statue of Liberty,
Central Park, and Times Square.
Note: “For example” is typically used to start a sentence; “such as” (more formal) and “like” (informal) are used in the middle of the sentence.
As such is used to avoid repeating information that was recently stated:
(a) I'm a working mother, and because I'm a working mother, I don't have much free time. This is not ideal because we repeat a phrase
(b) I'm a working mother, and as such, I don't have much free time.

Advice is a noun, and advise is a verb:
(a) She gave me some good advice.

There's also a pronunciation difference: advice has an “S” sound, and advise has a “Z” sound.
Don't make the common error of saying “advices” - the word advice is uncountable.
However, you can say “pieces of advice”:

12. Appraise / Apprise

(b) I have the opportunity to work in a reputed company.
Also, possibility is neutral - it means maybe the event will happen, and maybe it will not happen. The word opportunity is a little more positive, it expresses the possibility for something good. So we can use possibility with good or bad things, but opportunity is usually used only for good things:
(a) I'm worried about the possibility of losing my job.
(b) You should take that job. It's a great opportunity for your career.
The word chance is more informal, and it can be used for possibilities or opportunities!

Adjective + enough

21. Current / Present

Current and present refer to things happening now (not in the past or future). These two words are usually the same. Sometimes, current is used in the sense of "generally now" and present is oftenused more in the sense of "immediately now, in this place/moment."
Example- My brother currently lives in New York, but he is in Los Angeles at present.

22. Affect / Effect

(b) The medicine had an instant effect on the pain.

23. Allow / Let / Permit

LET + PERSON/THING + VERB (base form - without “to”)
Examples:
(a) I don't let my kids watch violent movies.
(b) Don't let the advertising expenses surpass $1000.
The simple past tense of let is also let; there is no change!
The verbs allow and permit are more formal ways to say “let.” However, with allow and permit, we use to + verb:

Permit is the most formal, let is the least formal, and allow is in the middle.

The verb treat is used for giving medical aid; making efforts to help a sick or injured person get better:

All of these words describe when two things are happening simultaneously (at the same time). Let's start with during and while.
Use during before a noun:
For Example (a) The people sitting in front of me were talking during the movie.
Use while before a subject + verb:
For Example (a) We'll buy the tickets while you wait in line for the popcorn.
Sometimes, when the subject of the two actions is the same, we eliminate the second mention of the subject:
For Example (a) I like to listen to music while I'm exercising.
= I like to listen to music while exercising.
We cannot do this when the subjects of the two actions are different:
Example- (a) I chopped the vegetables while my brother prepared the meat.
Two different subjects for the actions - “I” and “my brother”
Meanwhile is the same as while, but it is used only at the beginning of a sentence - and usually when there are two different subjects doing the two actions:
For Example (a) I was watching TV while my brother was studying.
= I was watching TV. Meanwhile, my brother was studying.
In the meantime usually implies you are doing an action while waiting for something else to happen. Example. (a) I will send you the text for the brochure tomorrow. In the meantime, you can start working on the graphics.

For Example-(a) I don't regard this as a problem; I regard it as an opportunity.
Regards (n.) is a greeting:

The phrases regarding and in/with regard to mean “related to / concerning the following topic”: Example- (a) Have you read the report regarding the economic crisis?
Regardless (adv.) means one thing is not affected by something else:
Example- (a) A champion keeps going, regardless of the difficulties.
Don't use the word “irregardless” - it doesn't exist; it is a common error in English.

36. Resolve / Solve

Do you solve a problem or resolve a problem?
The answer is both. Solve and resolve do have slightly different meanings, though.
To resolve something means to deal with and finish it in a satisfactory way:

To solve something means to find the CORRECT answer, or to fix it successfully:

Problems can be solved or resolved depending on their nature. When there are multiple opinions and points of view that must be reconciled, we usually use resolve:

When there is probably a correct answer, a successful solution that will eliminate the problem, we usually use solve:

Already is usually used in positive sentences.
Yet is usually used in questions and negative sentences.
For Example:

It shows that yet is used at the end of the question.
Now see the following Examples.
(a) Yes, I've already bought the tickets.
(b) No, I haven't packed the bags yet.
Use already in the positive answers, and yet in the negative answers.
There is one time you can use already in questions: it's when something happens earlier than expected.

40. Also / As well / Too

These words are all used to show similarity or sameness:
(a) Jerry plays soccer. Harry plays soccer, too.
(b) Jerry plays soccer. Harry also plays soccer.
(c) Jerry plays soccer. Harry plays soccer as well.
The only difference is in their placement in the sentence.
Too and as well are used at the end of a sentence. (As well is more formal than too). “Also” usually goes before the verb or adjective.

cement = uncountable

An object belongs IN a category, and belongs WITH other similar things.
