Over there; at a distance that you can see; an archaic or poetic way of saying 'that' or 'those' far away.
From Old English 'geon' meaning 'over there.' Related to 'yonder,' it's a Germanic word that survives mainly in Shakespeare and fantasy literature today.
Shakespeare loved this word—'What light through yonder window breaks?'—it sounds magical because it's ancient, making distant things seem mysterious and important!
