Notes:
There are 4 groups or families of verbs in Latin. These are called "conjugations."
The "to -form" of a verb [to walk, to love, to sit, to stand, to... ] is called the infinitive form. It looks like this:
ambulARE TO WALK
movĒre (e is long). TO MOVE
surgERE (e is short) TO RISE, GET UP NOTE: THESE INFINITIVES ALL END IN -RE
audIRE TO HEAR, LISTEN
To find the stem of a verb, the root element to which different endings are attached, one simply removes the -RE from the infinitive.
The infinitive helps you determine the conjugation to which a verb belongs.
1st conjugation infinitive ends in -ARE AMBULA
2nd conjugation ends in ERE (e is long) MOVĒ
3rd conjugation ends in ERE (e is short) SURGE
4th conjugation ends in IRE AUDI
The stem is also the singular command form. Now watch this video:
