The kanji 信 is a 形声文字 (keisei moji), which means it's a character that combines a semantic component (meaning) and a phonetic component (sound). The left side is 人 (nin/hito), meaning "person," and the right side is 言 (gen/koto), meaning "word" or "speech." Therefore, originally, the kanji's meaning referred to the idea of a person's words being trustworthy or believable. Over time, it developed to represent the broader concepts of trust, belief, and faith. The 人 (person) radical implies that trust comes from people, and the 言 (speech/words) radical signifies the importance of honesty and truthfulness.
