reinforce, re-enforce

You can reinforce your effort. You can reinforce your work colleagues. You can also reinforce concrete. You can’t re-enforce any of them. Reinforce means strengthen. It can be used in the physical sense and in the sense of encouraging or supporting people. It’s sometimes incorrectly written as re-enforce, which would mean “compel observance again”.

rein in

When you limit or control something you can be said to rein it in. Take care with the spelling. Sometimes people write “reign in” but that’s incorrect. You can’t reign unless you’re a monarch.
