Suffix · forms adjectives
Turns a noun into an adjective meaning "related to" or "belonging to": nation becomes national.
Written by Bryan López, English teacher · Updated
The suffix -al takes a noun and creates an adjective meaning "related to", "characteristic of" or "belonging to". From "nation" you get "national"; from "music" you get "musical"; from "origin" you get "original". It is one of the most frequent suffixes in academic, scientific and professional vocabulary. When you see a long adjective ending in -al, strip it off and look for the noun inside.
Some -al words work as both adjectives and nouns: an animal, a proposal, a signal, a trial, a journal. Context tells you which function the word is serving. The form is exactly the same.
Noun (usually Latin-origin) + al. No spelling changes.
When the base ends in -ic (logic, magic, music), the adjective may be -ical (logical, magical) or just -ic (magic, classic). Sometimes both forms coexist with slightly different meanings: economic (of the economy) vs economical (cost-saving).
-al/əl/ · soft, unstressed 'ul'

No consonant doubling. The suffix is simply -al or -ical: nation + al = national.
economic policy vs an economical car (one that uses little fuel). Two different adjectives.
tradition + al = traditional. Four syllables: tra-di-tion-al.
A trick to remember it
Think of national: nation + -al = relating to the nation. If you want to say something is "of" a thing, try -al: musical, natural.
