Make a verb with a suffix

1 · Learn

A noun names something and an adjective describes something. A verb can tell us what happens or what someone does. A suffix at the end of a word can help change its job: pure describes the water, but purify means make it pure.

Compare the adjective simple with the verb simplify, meaning make simpler. The noun apology names an expression of regret; apologise means express that regret. The noun motive names a reason; motivate means give someone a reason or encouragement to act. The endings -ify, -ise and -ate help form these verbs, but the root spelling may change. Not every word accepts every ending: do not invent simpleate.

2 · Worked example

In 'Please simplify the instructions', simplify is a verb because it tells someone what to do. Simple loses its final e before ify is added. In 'The instructions are simple', simple is an adjective describing the instructions. Adding letters is not enough: explain the change in meaning and word job.

3 · Your turn
