Note: We avoid the past continuous (was + seeing) with stative verbs, since these verbs have no clear start or finish as dynamic verbs do. Stative verbs (which represents mental processes, feelings, or internal states of existence), use the simple past conjugation or past perfect tenses or aspects.

Is "see" a regular or irregular verb?

Answer: See is an irregular verb— its past conjugations are saw and seen.

Note: Regular verbs end in -ed in the past tense. Any other verb ending is considered irregular.

While an irregular verb, 'see' shows a highly common verb-conjugation pattern. Similar to other verbs like take/took/taken, break/broke/broken, and wake/woke/woken, see uses different forms for past tense and past participle.

When to use "saw" vs. "seen"

I saw a shooting star last night.

I have seen that movie before.

The participle form of a verb (shown in the second sentence) uses the auxiliary verb have as a contraction, I've.

When auxiliaries like have or had appear in the same sentence as a past participle verb form, this indicates that the verb's aspect is in the present or past perfect, and not the simple past tense.

Remember, a participle always uses a helper verb to form the complete tense or aspect. Simple tenses, on the other hand, can stand on their own.
