Origin:
Old English twā (feminine and neuter) of Germanic origin; related to Dutch twee and German zwei, from an Indo-European root shared by Latin and Greek duo. Compare with twain

Do not confuse to with too or two. To usually means 'in the direction of' ( the next train to London); too means 'excessively' ( you’re driving too fast); two is the number between one and three.
