Origin:

Old English (adverb and preposition), of West Germanic origin; related to Dutch toe and German zu

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.
