I didn't see that coming.
Request some expert to clarify this doubt.
Two Important points :
1. When ever we change the tense of the verb, the first word of the verb only change into the respective tenses and all other be in their base form.
2. When we change a sentence into a negative form, we place not after the be verb, incase be verb is not there - then we use do. In fact "do" is assumed when there is no "be" verb. ( same is done in converting a sentence into a interrogative one)
She is coming ---- she is not coming : "not" is an adverb of frequency. "Not" being an adverb of frequency acts like all other adverbs of frequency -- be+adverb of frequency+main verb.
Messi has
always scored a goal against X -- be + adverb of frequency + main verb
when there are no "be" verb :
Original form : They do love to watch cricket ---- They love to watch cricket.(do is assumed here) --- They do not love to watch cricket.
So when we convert this into a past form, as per rule 1 - the first verb take the tense while all other remain in their base form ( plural present form) --> They did not love to watch Cricket.
So - I didn't saw ... is wrong. --- past form of "do not see" is "did not see"
This concept can also be applied here :
1. Does everyone has their book?
2. Does everyone has his book?
3. Does everyone have his book?
4. Does everyone have their book?
