口 — pictograph of an open mouth
口 is one of the oldest pictographs in Chinese, originally drawn as a simple outline of an open mouth. Its core meaning 'mouth' extended naturally to 'opening' or 'entrance', as in 入口 (entrance). It also serves as a common radical in characters related to speech, eating, or apertures.
才 — single component 才 (one stroke 一 + 亅 + 丿)
才 originally pictured a sprout breaking through the ground, symbolizing budding talent or potential. Over time it came to mean 'talent, ability' and also 'just now,' since a sprout marks a fresh beginning. It is itself a basic component used in characters like 材 and 财.
