The Spanish word 'chapapote', meaning 'tar' or 'bitumen', comes from the Nahuatl (Aztec) language. It originated from 'tzaucpopochtli', which was formed by combining two Nahuatl words: 'tzauctli' meaning 'glue' or 'adhesive', and 'popochtli' meaning 'perfume' or 'smoke'. The compound literally described a sticky, smoky substance - perfectly capturing the nature of tar or bitumen.

The word evolved from 'tzaucpopochtli' to 'chapopote' in Spanish, and then to the modern form 'chapapote'. This adaptation reflects the typical Spanish phonological changes when borrowing from Nahuatl, where 'tz' became 'ch' and the complex consonant clusters were simplified to make the word easier to pronounce in Spanish.

While 'chapapote' is a relatively unique word in Spanish derived from Nahuatl, there aren't many commonly used, simpler Spanish words that share its etymology. This is because it comes from a specific Nahuatl compound term that was borrowed directly into Spanish to describe this particular substance.

There aren't any common English words directly related to 'chapapote' since it comes from Nahuatl, a Native American language family that had little direct influence on English. English speakers would use words like 'tar' or 'bitumen', which have different etymological origins.
