The adverbial phrase kind of (or sort of) is very common in spoken English. It is often slurred when speaking to sound like "kinda". It is almost used as a crutch word to mean slightly, somewhat or in a sense.
That was kind of nice of him to help you like that — Fue bastante amable por su parte ayudarte así
Was his joke funny? - Kind of — ¿Fue gracioso su chiste? - Algo
He just kind of stared at me — Es como que se me quedó mirando
