Pronunciation: [ɡˈabɹə͡ʊ] (IPA) 
Gabbro, a term used in geology to describe a type of dark, coarse-grained igneous rock, has a few synonyms. For starters, it is commonly referred to as "black granite" due to its dark, dense appearance. Additionally, gabbro can be called "diabase," which is derived from the Greek words "diabasis," meaning "a crossing" or "passage," and "basalt," due to its compositional similarities to basaltic rocks. Another term used to describe gabbro is "norite," which is a more specific form of gabbro that contains higher levels of orthopyroxene and less clinopyroxene. Ultimately, while gabbro may be the most commonly used name for this rock type, there are several synonyms that can be used interchangeably for it.
