Yes — "brother" is a Third Grade sight word. Its "th" and unusual "o" sound (a short "u" sound instead of the expected short "o") make it worth practicing as a whole word.
My brother is two years older than me.
The "o" in "brother" doesn't make its typical short-"o" sound (as in "hot") — instead it sounds like a short "u" ("BRUH-ther"). This vowel-sound shift, shared with related words like "mother" and "other", is exactly the kind of irregularity that earns a word sight-word status.
Group "brother", "mother", and "other" together — all three share the same unexpected "o-sounds-like-u" pattern, reinforcing the exception as a small family rather than a one-off surprise.
