The Other Verbs
As promised here is a little more information on the Bases. This is by no means a comprehensive listing of the things the bases can do, particularly Base Te. However, this should give you a little bit of an edge when you are creating your own sentences.
Base 1: Exclamative. Often, you will hear someone say a Base 1 verb in a sharp and/or abrupt way.
Base 2: When changed into this base, the verb itself can become a noun. (this blew John Sensei's Brain supposedly when he first learned this.)
Base 3: Plain form. This base is the positive present tense of all verbs. This is also dictionary tense. All verbs are searched in this form.
Base 4: Command form. This is a very easily confused base. People either think it is more intense than it really is, or less intense than it actually is. For the most part. Base 4 is used in giving short and curt commands. They can be quite rude and should be used carefully.
Base 5: Let's Verb. Literally this is the way to say let's ____! You can change the verb into this base and literally say 'let's' anything.
Base Te: This base has a couple of meanings:
1.) Connecting sentences or clauses; used often to link a clause to another clause in which a reason for the previous clause is given.
2.) Base Te can also link verbs and adjectives exhaustively like と can do for nouns.
Base Ta: Past tense.
