1. ___please → dis-please ✔ → *displease* (to make unhappy)
✔️ dis-

2. ___hale → in-hale ✔ → *inhale* (to breathe in)
→ Also exhale — both are valid! But let’s check which one is more likely.
→ Since we have both “in-” and “ex-”, and “inhale” is very common…
✔️ in- (or possibly ex- for exhale — but let’s see if both can be used later)

⚠️ Wait — we might need to use exhale here if inhale is used elsewhere. But no other “hale” words. Let’s pick inhale for now.

Actually, let’s double-check:
- inhale = breathe in
- exhale = breathe out
Both are correct. But since we have in- and ex- available, and no conflict yet — we’ll choose inhale.

✔️ in-

*(But note: if you later need "ex-" for another word, you may swap. For now, it's fine.)*

3. ___wind → un-wind ✔ → *unwind* (to relax or loosen)
→ Also rewind — both possible.
→ Let’s pick unwind as it’s more common for relaxation.
✔️ un-
