How to form verbs from adjectives

In my earlier post, I discussed how nouns could be formed from adjectives. In today's blog, I will talk about the formation of verbs from adjectives.

Verbs can be formed from adjectives by:

1 adding 'en'

e.g. hard -->harden

soft -->soften

weak -- >weaken

broad -->broaden

smooth -- > smoothen

less -- > lessen

rich -->enrich

large-->enlarge

2 adding 'ise'

e.g. real --> realise

legal-->legalise

3 adding 'ify'

e.g. false -->falsify

null -->nullify

4 changing its spelling.

e.g. long -- > lengthen

strong -- > strengthen
