KanjiJLPT N1
View

perusal, see

Mnemonic

The retainer grabs a quill and sketches one sweeping line across the map. He climbs the tower to see the lands himself—his lord demands a complete view of every border, hill, and village before the war council.
Additional thoughts
Picture the retainer high in a tower, quill in hand, one panoramic line drawn on parchment as he sees the vast kingdom spread below. The act of viewing is formal and deliberate—an inspection for his lord.
Quick recall
A retainer with a quill draws one line, then sees the grand view from the tower.
