Peh is the seventeenth letter of the Hebrew alphabet. The name derives from the word peh פה - "mouth", and this was the original shape of the letter. As we've seen earlier, peh can alternate with bet, vav and mem.
Besides "mouth", peh can also mean "speech", "opening" and "portion" (as in pi shnayim פי שניים - "double".)

- כפי - like, as
- לפי - according to
- על פי - in accordance with
- אף על פי - although
