FUTURE TENSE, Active voice. Latin uses two sets of endings to show future tense. These depend on the conjugation of the verb.
FIRST AND SECOND CONJUGATION VERBS

amo amare terreo terrere (long -ere)

Both drop the -re from the second pr. part to form the root.

amabo I will love terreBO I will scare
amabis you will love terreBIS you will scare
amabit he will love terreBIT he will scare
amabimus we will love terreBIMUS we will scare
amabitis y’all will love terreBITIS y’all will scare
amabunt they will love terreBUNT they will scare

Memory trick: Third and Fourth conjugations have no "bo" in their future. Third conjugation causes problems, as it always does.
duco ducere
Drop the -ere from the second pr. part and add the endings.
ducAM I will lead ducEMUS we will lead
ducES You will lead ducETIS y’all will lead
ducET He will lead ducENT they will lead

Fourth conjugation
audio audire
Drop the -re from the 2nd pr. part
audiAM I will hear audiEMUS we will hear
audiES you will hear audiETIS y’all will hear
audiET he will hear audiENT they will hear

Third -io verbs
capio capere
Drop the -re from the 2nd pr. part. e changes to an I.
It is as if they are -ire verbs.
capiAM I will take capiEMUS We will take
capiES you will take capiETIS y’all will take
capiET he will take capiENT they will take
