Language of Parts: SC 3.1.2

My page has (i.e, and etc.,) which is both Latin. Language of Parts suggets I might not need it: See the example below as part of SC 3.1.2.
 
Individual words or phrases in one language can become part of another language. For example, "rendezvous" is a French word that has been adopted in English, appears in English dictionaries, and is properly pronounced by English screen readers. Hence a passage of English text may contain the word "rendezvous" without specifying that its human language is French and still satisfy this Success Criterion. 
 
Do I need the lang tag for i.e., or etc., neither, or both?
