The principal parts usually adhere to one of the following patterns:

** {{lang|la|doceō, docēre, docuī, doctum}} "to teach, to instruct"
** {{lang|la|iaceō, iacēre, iacuī, iacitum}} "to lie (on the ground/bed)"
** {{lang|la|mereō, merēre, meruī, meritum}} "to deserve"

In verbs with perfect in ''-vī'', [[syncope (phonology)|syncopated]] (i.e. abbreviated) forms are common, such as {{lang|la|dēlēram, dēlēssem, dēlēstī}} for {{lang|la|dēlēveram, dēlēvissem, dēlēvistī}}.<ref name=":1">Gildersleeve & Lodge (1895), p. 90.</ref>

* The perfect has the suffix ''–īvī''. Example:
** {{lang|la|cieō, ciēre, cīvī, citum}} "to arouse, to stir"

* The perfect has the suffix ''-sī'' (which combines with a preceding ''c'' or ''g'' to ''–xī''). Examples:
** {{lang|la|ārdeō, ārdēre, ārsī, ārsum}} "to burn"
** {{lang|la|augeō, augēre, auxī, auctum}} "to increase, to enlarge"
** {{lang|la|haereō, haerēre, haesī, haesum}} "to stick, to adhere, to get stuck"

** {{lang|la|caveō, cavēre, cāvī, cautum}} "to be cautious"

:* {{lang|la|mereor, merērī, meritus sum}} "to deserve"

:* {{lang|la|audeō, audēre, ausus sum}} "to dare"
