There is a lot of information in Wikipedia. Some is correct, and some is false.
Use "was" when referring to a singular subject, and use "were" when referring to plural subjects or the second person singular (you). For example: "He was happy" (singular subject) vs. "They were happy" (plural subject) or "If I were you, I would go" (second person singular).
Only in the singular second-person (you were). A singular subject in the first and third persons uses "was."
Don't know what an insubordinate clause is, but I do know that "was" is singular, and "were" is plural. 2nd person (you) is an exception, you use "were" in both singular and plural: You were (singular, one person) You were (plural, all of you) Otherwise, like I said, you just use "was" in 1st person and 3rd person singular, and "were" in 1st and 3rd plural: I was (1st person singular) He/she/it was (3rd person singular) We were (1st person plural) They were (3rd person plural)
Is and are are both present tense be verbs. Is is the singular form and are is the plural form.He is always late.They are always early.Use is when you have a singular subject ( that is not I, then use I am).Use are when you have a plural subject.
Use "are not" if the subject is plural. Use "is not" if the subject is singular. Some examples:Jack is not doing his homework.Jack and Jill are not doing their homework.

Use 'is' when he/she/it or a singular noun is the subject. He is my cousin. She is my cousin. It is mine. The policeman is my brother. -- policeman = singular noun subject.
When you have a singular subject, you use is.Just as if you have a plural subject, you use are.For example,The dog (singular) is (singular) outside in the yard.Whereas,The dogs (plural) are (plural) playing in the grass.Hope this helps ! :)
Has is the third-person singular form of have. If the subject is singular, use has. If it is plural, use have. For example, The boy has some candy. The boys have some candy. The boy has gone home. The boys have gone home. Have is also the imperative form. For example, Have some candy! If the subject is the first-person personal pronoun "I" or the second-person personal pronoun "you" then use "have" instead of "has." I have some candy You have some candy. We have some candy. They have some candy. He has some candy. She has some candy. It has some candy. (This is because he/she/it are third person singular.)
