noun

biological younger brother

Used to specify a younger brother by blood, as opposed to a brother-in-law or stepbrother. Often used in formal or explanatory contexts.

義ぎ弟てい
義弟 means 'brother-in-law' (younger) or 'adopted younger brother', contrasting with 実弟 which specifies a blood relationship.
弟おとうと
弟 is the common word for 'younger brother' and does not explicitly emphasize the biological relationship, while 実弟 makes the blood relation explicit.

Compound of 実 (じつ, 'real, true, biological') and 弟 (てい, 'younger brother'). The reading じってい is a standard on'yomi combination.
