English: Homonyms: syntax vs sin tax

Self-tutoring about English: the tutor notices another pair of homonyms…

Calling syntax and sin tax homonyms might be a stretch, since sin tax is two words. People might hear them similarly, however.

syntax: the rules of order and construction in a language.

sin tax: tax on items considered best not to consume. Alcohol, cigarettes, and even gasoline can be examples of goods whose price includes sin tax.
