Stouthearted means brave and steady — not the flashy bravery of running into danger, but the kind that keeps going when things are hard and does not give up. The picture inside the word is of a heart that is strong and solid, so it holds up under weight. The important thing for a student is the flavour, not the meaning. This word is old-fashioned and a bit grand. It belongs to adventure stories, war songs, old poems and speeches — "stouthearted men" is the title of a famous old song, and that tells you the register exactly. If you used it about a colleague at work, people would smile, because it would sound like you were quoting something. That said, English speakers do use it that way on purpose, gently teasing: "my stouthearted little brother finally went to the dentist." It is worth knowing because it shows you an older sense of stout that is otherwise hidden. Today stout mostly means fat, in a polite way — "a stout gentleman". But its older meaning was strong, solid, unyielding, and that older meaning is the one alive here and in phrases like "stout resistance" or "a stout pair of boots".
