KanjiJLPT N4
Wide

wide, broad, spacious

Mnemonic

Your veranda is so wide that someone has pitched a tent right in the middle of it — and there's still acres of space left. The tent looks comically tiny against the vast veranda stretching out endlessly in every direction. Now that's wide.
Additional thoughts
Picture your own porch suddenly expanding to football-field size, a little camping tent sitting there looking absurd. The contrast between the tiny tent and the enormous veranda locks in the sense of wideness.
Quick recall
A veranda so wide a whole tent fits on it with room to spare.
