What does detainable mean?
"Detainable" is a formal adjective describing someone or something capable of being detained — that is, legally held in custody or otherwise prevented from leaving. It appears almost exclusively in legal, governmental, and administrative contexts: immigration law, criminal procedure, and national-security legislation. When a court declares a person "not lawfully detainable," it is ruling that authorities lack the legal power to keep them in custody. The word derives from "detain," which traces back through Old French to the Latin detinēre, "to hold back or keep." Because its use implies an official power to confine, the term carries a serious, institutional connotation; it is rarely heard in casual conversation, but it is indispensable wherever the boundaries of lawful custody are being defined or contested.

Etymology of detainable
"Detainable" is formed from the verb "detain" plus the adjectival suffix "-able." "Detain" came into English from Anglo-Norman and Old French détenir in the late Middle Ages, ultimately from the Latin compound detinēre, formed from dē- ("away, from") and tenēre ("to hold"). The same Latin root tenēre gives English words such as retain, contain, and tenacious.
How detainable is actually used
