old enough / tall enough

Grammar notes

Enough Means As Much As You Need

Use adjective + enough when the degree is sufficient. It shows that something reaches the needed level. Unlike too, this pattern says the amount is enough, not too much.

• Example: She is tall enough to reach it.
• Example: The room is big enough for us.

Quick Rule

• adjective + enough
• enough comes after the adjective

The meaning is simple: it reaches the line, and that is enough.
