Question

Fill in the blank with the most appropriate word.
May I _____ to you tomorrow?
a. seeing
b. to see
c. seen
d. see

Answer 1

Hint:
 Look for pointers suggesting which verb to use in the blank as determined by the modal auxiliary. The sentence simply asks a question. These pointers are indicators of a certain tense.

Complete answer:
The modal auxiliary ‘may’ is unique in its usage. It is used for questions frequently as well as to indicate possibility. But, when this modal verb is used, no other fully conjugated verb can be used without an infinitive/a bare infinitive. So, it is grammatically incorrect to use only a fully conjugated verb in the given sentence. We must use a bare infinitive. A bare infinitive is an infinitive written without the determiner ‘to’.

Now, we know what we are looking for. Let’s look at the given options-
a. seeing - This verb is in the continuous form. This is the continuous tense of the verb ‘see’. Since this is a conjugated verb, it cannot be used in the given sentence. This is not the required answer. So, this is an incorrect option.
b. to see - This verb is in the full infinitive form. This is not the required infinitive form as this along with ‘to’ cannot be used in the given sentence. This is not the required answer. So, this is an incorrect option.
c. seen - This verb is the past participle of the verb ‘see’. Since this is a conjugated verb, it cannot be used in the given sentence. This is not the required answer. So, this is an incorrect option.
d. see - This verb is the bare infinitive version of the given verb. This is the required infinitive form. This fits perfectly into the given sentence. This is the required answer. So, this is the correct option.

Note:
 We usually use the word ‘may’ to ask someone a question in a formal way. This means that the person is asking about a possibility. The word ‘tomorrow’ should help with the tense.
