The word 'welcome' has a transparently literal origin in Old English. It is a compound of 'wilcuma', where 'wil-' meant 'pleasure, desire' (related to 'will') and 'cuma' meant 'guest, comer'. Thus, a 'wilcuma' was a person whose arrival was pleasing or desired. Over time, the spelling shifted to 'welcome', and its function broadened from a noun for the desirable guest to an expression of greeting, a description of the reception, and the act of greeting itself. The core logic connecting a wished-for arrival to a friendly reception remains perfectly clear in the modern word.

Structure: wel (wish, desire) + come (to arrive) 'wel' originates from Old English 'wela' (wealth, well-being) and functions as a root conveying the sense of 'good' or 'well'. 'come' originates from Old English 'cuman' (to come, arrive) and functions as the core verb root.
