The kanji character 指 primarily means "finger" or "to point." It refers to the individual digits on the hand, as well as the action of indicating something with a finger. It can also extend to metaphorical uses related to direction or instruction.

Sorry, I do not have enough information to analyze the correspondence with your native language.

The kanji 指 is a phono-semantic compound (形声文字, keisei moji). The left side is a radical called 手 (て, te), meaning "hand". The right side is 旨 (し, shi), which originally meant "taste" or "purpose". The combination of these two elements creates 指, expressing a relationship to the hand that relates to the action of pointing, like the finger is the "purpose" of the hand. Over time, it came to represent "finger" and "to point" because the hand uses a finger for these purposes.
