ORIGIN late Middle English (denoting a board strewn with sand on which to draw figures): from Latin, from Greek abax, abak- 'slab, drawing board,' of Semitic origin; probably related to Hebrew ' āḇāq 'dust.'
The Greek word abax, which refers to a counting board.
Abacus is not an acronym. The word passed through Latin, Greek and Hebrew from Mesopotamian where it meant "counting board".
It comes from the Greek word "abakos", which means "counting board".
Google translator states it as "ávakas" - pronounced a-va-cas"
Yes is does. The original word is "kachlika" for the little stones that the ancient Greeks used as a sort of abacus.
Hypno -- the greek word for sleep.
The abacus is actually Mesopotamian in origin and so it was invented around the time of Mesopotamia.
From the Greek word "synopsis".
From the Greek word for "change."
Around 2500BC the first Abacus appeared in Sumaria. It arrived in Persia about 600BC. The Greek Abacus is recorded to have been in use about 500BC
The possessive form of the word "abacus" is "abacus's." This follows the general rule of adding an apostrophe and "s" to singular nouns to indicate ownership. For example, you might say "the abacus's beads" to refer to the beads belonging to the abacus.
That abacus is so old fashioned.
