The word sulphanilic acid is derived from the combination of two components: sulphanil and acid.
The term sulphanil originates from sulfanil, which is derived from sulfanilamid. Sulfanilamid itself was created by combining sulfur and aniline.
The word acid comes from the Latin term acidus, meaning sour.
