“How come” is a very common phrase in spoken English. It is used to ask why something happened, especially when you are surprised or curious. It is more informal than “why,” so people use it in daily conversations with friends, family, or colleagues.
For example, if your friend didn’t come to a party, you might ask, “How come you didn’t come?” It sounds natural and friendly.
The special thing about “how come” is that we don’t change the word order like we do in questions with “why.” This makes it easier to use in speaking.
