Great question, Liz. You are correct. "Need" can be used as a main verb or modal verb. Need as a main verb is often followed by a to-infinitive and expresses that something is necessary. "I need to take a rest." ("Rest" is being used as a noun here) Or simply, "I need to rest." (main verb + infinitive) Since the word "rest" can be used as a verb or a noun you can also say it this way: "I need rest." (Rest as a noun: an instance or period of relaxing or ceasing to engage in strenuous or stressful activity.) I'm not sure how the word "rest" would be used with need as a modal verb. Modal verbs are used with negative sentences, interrogative sentences, or in affirmative sentences with a negative meaning. For example: "No one need be surprised by his poor behavior." "Need" can be used in the positive form as a modal verb, but it is uncommon and typically too formal for everyday speech. I hope this helps.

"I need to take a rest" is the correct answer. In this situation, there are 2 verbs together "need" and "to take." The first verb is conjugated "I need." The second verb is in its infinitive form: "to take." This is a common pattern when two verbs are used together. For example: I want to eat noodles. I like to read stories. I need to exercise today. I love to go to the movies. You can also use "need" in a negative sentence. For example: I don't need any rice. I don't need much money. I won't need my car tomorrow.

Either: - I need a rest. - I need to take a rest. Both these expressions convey an equivalent meaning. You often will have options. More colloquial would be, "I need a rest", which might be said while you're out of breath or otherwise exhausted from work or effort. If you say, "I need to take a rest", you would more likely be referring to the future, seeing as how it's more prosaic. In everyday spoken language, the shorter or simpler method that conveys the same or equivalent sense would always be more common. Hope this helps you decide what to use.

Hi Liz, B is the best way to say this. "I need to take a rest." Need always must have the word "to" after it, if what the person needs is *to do* something. If what the person needs is a thing like *food* You can say "I need food". By the way need is technically not a modal verb. Anyways I'll give you an example. If someone is hungry they can say; "I need to eat." OR "I need food." In the same way, you can say "I need to rest" or " I need rest" Feel free to message me any with any other questions
