The word 躬行 is formed by combining the character 躬, which is composed of 身 (body) and 弓 (bow, serving as a phonetic component), meaning "personally" or "in person", with the character 行, meaning "to act" or "to do". Together, they create a compound where 躬 modifies 行 to convey the meaning of "personally practicing" or "carrying out oneself".
