Will in English: Spontaneous Decisions, Predictions, and Promises

Will + base verb never changes form, no matter the subject: I will, she will, they will.

Will is used for decisions you make at the moment of speaking, predictions based on opinion (without solid evidence), promises, and offers. It never changes form: will is the same for every subject.

The uses of will

A spontaneous decision, made right at the moment of speaking: "I'm thirsty. I'll get some water." A prediction based on opinion, without solid evidence: "I think it will rain tomorrow." Promises: "I will always love you." Offers: "I'll carry that for you."

Will never changes form

Unlike other verbs, will is exactly the same for every subject: I will, you will, he will, she will, we will, they will. You never say "he wills" or add -s to it.

Common mistakes learners make

Using going to for a spontaneous decision, when it should be will: if you decide something right at the moment of speaking, you use will, not going to (going to is for plans already decided beforehand). It's also common to try to conjugate will like a regular verb, adding -s with he/she/it.
