Grammar Notes & Usage Tips

Use 太る in the plain form like "太った" (I gained weight) to talk casually about past weight gain—just be sure not to say "太るを" (wrong particle), since it doesn't take を.
To describe someone who is gaining weight, say "[name]が太ってきた", using が to mark the person getting heavier.
Don’t confuse 太る (to gain weight) with 太い (fat/thick); 太る is a verb (an action), while 太い is an adjective (a description).
