Normally, it’s very easy to make the verb+ing form. We add ‘ing’ to the infinitive.

• be → being
• sleep → sleeping

When the verb ends with ‘e’, we usually drop the ‘e’ before we add ‘ing’. There are many, many verbs like this.

• share → sharing
• smile → smiling
• phone → phoning
• use → using
• wake → waking
• write → writing
• serve → serving
• realise → realising
• practise → practising
• move → moving
• live → living
• ignore → ignoring
• invite → inviting
• imagine → imagining
• give → giving
• smoke → smoking
• save → saving
• make → making
• have → having
• take → taking
• arrive → arriving

Sometimes we have to double the last consonant.

• swim → swimming
• run → running
• begin → beginning
• fit → fitting
• forget → forgetting
• get → getting
• hit → hitting
• let → letting
• plan → planning
• prefer → preferring
• put → putting
• set → setting
• sit → sitting
• shut → shutting
• stop → stopping
• travel → travelling
• win → winning

When the verb ends in -ie, we change -ie to -y before we add -ing.

• die → dying
• lie → lying
