I notice after the Te form verb there is usually a います or きます. Is every masu verb be able to follow a Te form?

Question

夕方になって少し雲が出てきました。

what is the grammar point of this？

Answer 1

No. There are only a little over a dozen verbs that work this way.

います, きます, みます, あげます and so on, after a te-form, are called subsidiary verbs. They add a certain meaning to the first verb. For example:

• 食べます + います = 食べています = "is eating" or "has (already) eaten"
• 食べます + みます = 食べてみます = "to try eating"

See: What is a subsidiary verb?

There are many related questions about (-て)いる and (-て)くる on this site, including:

• Does Vて+いる always mean an action already completed?
• Difference between -ていく and -てくる

But since every subsidiary verb is an important topic, your textbook (if you have one) certainly has an explanation for each of them, so I recommend reading them first.
