al-Qaeda

The term "al-Qaeda" entered English directly from Arabic in the late 20th century as the name of the militant group. It is not a constructed English word from classical roots but a borrowed phrase whose literal meaning, "the base," refers to the group's foundational role or training base for jihadists as originally conceived. The adoption of this specific Arabic name into global English lexicon exemplifies how geopolitical events can transform a foreign phrase into a household term with highly specific and charged connotations, detached from its mundane literal meaning in the source language.

This is a loanword from Arabic. In the original Arabic, "al-Qaeda" (القاعدة) is a phrase meaning "the base" or "the foundation," composed of the definite article "al-" (the) and the noun "qaeda" (base, foundation). In English usage, it is treated as an unsegmentable proper noun.
