Grammar question... well, sort of?

The words such as will, would, shall, should, can, could, etc are called auxiliary verbs or helping verbs?

And in the sentence "I should have known better", is "should" an auxiliary/helping verb or "should have" is?

If the latter one is, what the words such as "should" or "can" that follows by a verb (root word/present tence form) called?

    helping verbs is a term that is used to mean auxiliary verbs. Just a simpler term, less "officious". You could call it a kiddy term (it is often how the verbs are taught to young students, as "helping" verbs). The meanings are identical though. Some auxiliary verbs fall into a class called modals, and that includes the conditionals and similar such as should could must might etc. They have their own particular rules of usage.

    Auxiliary verbs are the same thing as helping verbs. Should is a modal auxiliary verb, as are would, could, can, ought, must, may, might, etc. Have is a tense-indicating auxiliary verb, as are has, had, was, were, will be, etc.

    "Should" is one auxiliary verb in that sentence; specifically, it's a "modal" verb, expressing things like possibility, duty, reality/unreality, etc. Then "have" is a SECOND auxiliary verb, expressing the tense of the main verb, which is "to have."
