The phrase "tend to verb" in English grammar refers to a construction where the word "tend" is followed by an infinitive verb, which usually expresses a habitual action or a general inclination. This construction is used to indicate that something often happens, that there is a likelihood or propensity for something to occur, but it's not absolute.
For example:
- "I tend to drink coffee in the morning." (This means that the speaker usually drinks coffee in the morning, but it's not a strict rule.)
- "Plants tend to grow towards the light." (This means that it's a general tendency for plants, but not all plants might do this under all circumstances.)
It's a way of expressing a general habit or tendency without making a definitive statement that it always happens.
