T NT

H/S/it they

1st congregation - are

amo, amare, amavi, amatus / To love

Get the second one, amare, and take out the “RE”

Stem - Ama

\
Ama - o

Since you can’t pronounce “ao” just eliminate the a, but keep the a for the rest.

Am - o Ama - mus

\
Ama - s Ama - tis

\
Ama- t Ama - nt

2nd congregation - ire

scio, scire, scivi, scius / know

get the second set of word, scire, and take out the RE.

stem - Sci

sci - o sci - mus

\
sci- s sci - tis

sci - nt

since the 2nd declension can’t have an “i” next to an “n” you must replace it with a “u”

sci - t sc - u - nt

3rd Congregation - ere

cano, canere, canesi, canetus / play (an instroment)

get the second set of word, canere, and take out the ERE. But, you can’t let it sound like “cans” or “cant” so you add an “I” on the end of it. On the last one, on plural, just replace the “i” with a “U”

stem - can (i)

can - o can - i - mus

can - i - s can - i - tis

can - i- t can - u - nt
