shortcoming; fault; imperfection
Humble expression used to acknowledge one's own shortcomings or areas for improvement, often in formal apologies or self-assessments.
There are many shortcomings on my part, but I ask for your kind understanding.
至らぬ点をお詫び申し上げます。
I apologize for my shortcomings.
From 至る (itaru, 'to reach, to be complete') in its negative form 至らぬ (itaranu, 'not reaching, incomplete') + 点 (ten, 'point, aspect'). Literally 'points where one has not reached (perfection)'.
