如 — woman radical 女 + mouth 口
Originally a phono-semantic compound where 女 (woman) suggested compliance and 口 (mouth) indicated speaking or following orders. The early sense was 'to follow' or 'to comply with what is said,' which extended to 'to be like' or 'as if.' Modern uses like 'if' and 'such as' grew from this comparative meaning.
愿 — 原 (source) + 心 (heart)
A semantic-phonetic compound. The heart radical 心 carries the meaning of inner feeling or wish, while 原 (yuán, 'source/plain') supplies the sound. Together they depict a wish welling up from the heart, giving the senses 'to wish, to be willing'.
以 — phonetic 㠯 (plow/tool) + 人 (person)
Originally a pictograph of a hand-held plow or tool (㠯), later combined with 人 (person) to suggest 'using' something. The core meaning 'to use' extended metaphorically to 'by means of', 'with', and 'because of'. In modern Chinese it functions mainly as a grammatical particle.
