What does the word Gomorrah mean?

In the Old Testament Sodom and Gomorrah were two cities destroyed by God as a punishment for the wickedness of their inhabitants. See Genesis 19:24
In Hebrew, it is actually pronounced 'Amorah, with a deep guttural first vowel. The Greeks, unused to the Hebrew epiglottal letter, transliterated it as a "g."
The word is related to Omer and Areimah (both of which have the same first guttural). Omer means "a measure," or "a sheaf (of grain)," and Areimah means "a pile." Some linguists say that the root word also means "deep" or "copious."

All of the above allude to the famed agricultural bounty of the area around Gomorrah and its sister cities, until God smote them (Genesis 13:10).
