Inside Pocket
noun
Your inside ポケット is your inside pocket.
内ポケット commonly refers to the inside pockets of things like jackets or suits, where you might keep valuables, as in 内ポケットにスマホを入れる (put one's smartphone in one's inner pocket).
This word uses the kun'yomi for the kanji. You've seen that reading with the vocab word 内, but here's a mnemonic just in case you forgot:
You look in your inside pocket, and… Ooh, cheese (うち)! Can this really be? You check again just to be sure it wasn't a mirage, and… Ooh, cheese! Yup, it's still there in your inside pocket. What a pleasant surprise.
