regard: [14] The notions of ‘looking at something, keeping it in sight’ and ‘guarding it’ are closely linked, and often coexist in single words. Watch is an example, and so was Old French garder, ancestor of English guard. Addition of the prefix re- ‘back’ produced regarder ‘look back at, keep one’s eyes on’, hence simply ‘look at’. The Anglo-Norman version of the word gave English reward. => guard, reward, ward
