〜させる

make / let (causative)

N3causation

〜させる expresses make / let (causative) — connecting cause and effect in Japanese. Japanese distinguishes between different types of causal relationships, from neutral explanations to blame or gratitude, and choosing the right expression conveys important nuance.

This is an upper-intermediate pattern common in natural conversation and media like news, novels, and dramas.

Structure

G1: う → あ-row + せる / G2: る → させる

Common Mistakes#

  1. Using 〜させる interchangeably with 使役形 — These patterns are similar but not identical. 使役形 (causative (make/let do)) may be preferred in different contexts or registers.
  2. Wrong verb group conjugation — Group 1 and Group 2 verbs conjugate differently. Common pitfall: treating Group 1 verbs ending in る (like 帰る) as Group 2 verbs.
