Origin

The character 駄 combines the horse radical 馬 on the left, which establishes that this character relates to horses, with 太 on the right, which serves as a sound hint for pronunciation. Historically, pack horses were used to carry goods and cargo, and the character came to mean a horse load or something transported by horse. Over time, the meaning extended to describe things as burdensome or trivial, perhaps because carrying loads on pack horses was seen as a mundane task. The 太 component doesn't contribute to the meaning but simply signals how the character should be pronounced.
