What is a suffix?

An illustration of a young girl smiling.

A suffix is a letter or group of letters that goes on the end of a word and changes its meaning.

Adding the suffix -ing to the end of a noun can change it into a verb.

For example:

garden + -ing 鈫 gardening

Adding the suffix -ed to a verb can form the past tense of that verb.

For example:

jump + -ed 鈫 jumped

Past tense

The past tense is used for things that have already happened.

Past tense verbs often end in -ed.

For example:

I walked to the shop.

However, not all past tenses are written like this as there are exceptions which need to be learned separately.

For example:

I bent down to pick up a penny.

The correct past tense of the verb to bend is 'bent' not 'bended'.

She swam three lengths in the swimming pool.

'Swam' is the correct past tense of the verb to swim, not 'swimmed'.

Present tense

The present tense is used when something is happening now or happens regularly.

Present tense verbs can end in -ing and when they do, they have 'am', 'is' or 'are' before them.

For example:

I am walking to the shop.

or

They are going to see their friends.

Spelling rules when forming tenses

There are some spelling rules to think about when you add the suffixes -ing and -ed to verbs.

1. For words ending in two consonants, just add the suffix to the root word. For example:

walk + -ed 鈫 walked

or

walk + -ing鈫 walking

2. For words that end in a short vowel sound followed by a consonant, you need to double the last letter then add the suffix. For example:

mop + -ed 鈫 mopped

or

mop + -ing 鈫 mopping

3. For words ending in a consonant followed by an 鈥檈鈥, you need to drop the 鈥榚鈥 before you add the suffix. For example:

love + -ed 鈫 loved

or

love + -ing 鈫 loving

4. For words that end in a consonant and a 鈥榶鈥, change the 鈥榶鈥 to an 鈥榠鈥 and then add the suffix. For example:

cry + -ed 鈫 cried

For -ing, you keep the original 鈥榶鈥 in the root so that you don鈥檛 end up with a double 鈥榠鈥. For example:

cry + -ing 鈫 crying
