ichidan verb, transitive verb
Rare, literary verb meaning to foresee or mentally prepare for something. In modern Japanese, 予想する or 予期する are far more common.
彼は困難を思い設けて、事前に対策を練った。
He anticipated difficulties and worked out countermeasures in advance.
Compound of 思い (thought) and 設ける (to prepare, establish). The exact historical derivation is uncertain; it appears in older literary sources.
