Future Simple (will)

WHEN TO USE

COMMON MISTAKES
I will to call you later.
I will call you later.
After 'will', use the base form — NOT 'to + verb'
I will going to the party tonight.
I will go to the party tonight.
Use 'will + base verb', not 'will + going to'
Tip
A quick way to distinguish 'will' from 'going to': if you decided BEFORE the moment of speaking → use 'going to'. If you decided AT the moment of speaking → use 'will'.
