Add -tor for a doer, -tio for an action, -tas for a quality and -ulus for something small.

How It Works

EndingJobLatinEnglish cousin
-torthe doeractor (from agere), pastor (from pascere)actor, pastor
-tiothe actionactio (from agere), oratio (from orare)action, oration
-tasthe qualitylibertas (from liber), civitas (from civis)liberty, city
-ulussomething smallhortulus (from hortus), filiolus (from filius)circle, globule

The endings -tor and -tio are added to the fourth dictionary form without -um: actum gives actor and actio.

The small ending is -ulus, or -olus after a vowel, as in filiolus. Words in -tas and -tio are feminine, and words in -tor are masculine.
