Origin of the word ch'ti
The word ch'ti, chtimi or ch'timi to designate the Picard language was invented during the First World War by Poilus from non-Picard speaking areas to refer to their brothers in arms from Picardy and Nord-Pas-de-Calais. It is an onomatopoeia created based on the frequent use of the /ʃ/ (ch-) phoneme and of the /ʃti/ (chti) sound in Picard: "ch'ti" means the one, as in the sentence "ch'est chti qui a fait cha" (he is the one who has done that), for instance.
