In continuous tenses and gerunds, we mostly add -ing to the main verb but there are some exceptions to study.
When the verb ends in letter E, we drop it and then we add -ing. For example, write – writing. But the -ing form of the verb “see” is spelled S E E I N G.
For verbs ending in consonant plus accented vowel plus consonant, we double the last consonant before adding -ing, such as in swim – swimming.
In traditional British English, verbs ending in letter L, double that letter before writing -ing. Travel – travelling.
Verbs ending in -IE, drop the -IE and take letter Y plus -ing. Example: Lie – lying.
