to go or going? (A2 Grammar)

Some verbs are followed by to and the base verb: want, decide, plan, hope, need, would like. So you want to go, not want going.

want to go (to + verb)

enjoy going (verb + -ing)

Other verbs are followed by the -ing form: enjoy, finish, mind, avoid, keep, practice. So you enjoy cooking, not enjoy to cook.

making the -ing form

You already spell the -ing form this way: add -ing to the base verb (eat → eating, read → reading), and drop a silent -e first (write → writing, take → taking, move → moving, not writeing). The spelling does not change here — what is new is which verbs are followed by it.
