IPA: /hɔrnˈblɛndɪk/
KK: /hɔrnˈblɛndɪk/
Relating to or made up mostly of a mineral called hornblende, which is typically dark in color and found in many types of rocks.
The geologist identified the rock as hornblendic due to its dark, shiny crystals.
Hornblendic is derived from 'hornblende' (from German 'Hornblende', meaning horn-like and to blend), with the suffix '-ic' (meaning pertaining to). The term describes something that is related to or characteristic of hornblende, a type of mineral.
Think of 'hornblende' as a mineral that has a 'horn-like' appearance, and the '-ic' suffix indicates that it pertains to that mineral.
