'tokenized' originates from English, specifically the word 'token' combined with the verb-forming suffix '-ize'; 'token' ultimately comes from Old English 'tacen' meaning 'sign', and the suffix '-ize' derives (via Latin/French) from Greek '-izein' meaning 'to make or to render'.

'token' changed from Old English 'tacen' into Middle English 'token'; the productive verb-forming suffix '-ize' (from Greek/Latin/French) was added to form 'tokenize' in modern English, and the past/past-participle form 'tokenized' followed standard English verb inflection.

Initially, 'token' meant a 'sign' or 'symbol'; over time, combining it with '-ize' produced a verb meaning 'to make into a token' or 'to convert into a sign/representation'. In modern use 'tokenize/tokenized' has specialized senses such as converting text into tokens (NLP) or replacing sensitive data with tokens (data security).
