- misalign
to put into a wrong or crooked position

用法筆記
Distinguish from sense 5: sense 6 emphasises internal honesty and authenticity (being true to YOURSELF or your beliefs), while sense 5 emphasises external loyalty (being true to ANOTHER PERSON or cause). The preposition 'to' is essential — 'true [someone]' without 'to' does not convey this meaning.
