become: [OE] Become is a compound verb found in other Germanic languages (German bekommen, for instance, and Dutch bekomen), which points to a prehistoric Germanic source *bikweman, based on *kweman, source of English come. Originally it meant simply ‘come, arrive’, but the modern senses ‘come to be’ and ‘be suitable’ had developed by the 12th century. A parallel semantic development occurred in French: Latin dēvenīre meant ‘come’, but its modern French descendant devenir means ‘become’. => come
Old English becuman "happen, come about," also "meet with, arrive," from Proto-Germanic *bikweman "become" (cognates: Dutch bekomen, Old High German biqueman "obtain," German bekommen, Gothic biquiman). A compound of be- and come; it drove out Old English weorðan. Meaning "to look well" is early 14c., from earlier sense of "to agree with, be fitting" (early 13c.).
