For reasons I won’t explain, I was thinking about the word(s) photograph and photo. English speakers (and I suspect speakers of most languages) often shorten words like these. Investigating using Google Ngrams, I found that, not surprisingly, photograph was used more commonly for most of the word’s history, and that photo overtook it in 1984 (specifying usage as a noun). My preliminary theory is that photograph declined with the rise of digital photo instead of digital photograph, but Ngrams shows that those two phrases are too late and comparatively too little used to have much of an effect overall.
Similar is/are telephone and phone, for which the latter became more common (as a noun) as recently as 1998. This is plausibly connected to the rise of cell phone and mobile phone instead of cell telephone and mobile telephone, which basically no-one ever used or uses, but phone had been rising in usage since the 1960s.
Compare the verbs photograph and *photo and telephone and phone (which switched in 1995). Not surprisingly, Ngrams does not record photo as a verb, but surprisingly also does not record photograph, either. At first I thought I’d mis-spelled it, but no, that’s the result. Also not surprisingly, take a photo increased steadily from about 1980 and sharply from about 2000.
Some languages shorten words even more. In Korean, 디지털 카메라 (di-ji-teol ka-me-ra) become 디카 (di-ka) and if 셀프 카메라 봉 (sel-peu ka-me-ra bong) ever existed, it quickly because 셀카봉 (sel-ka-bong, selfie stick).
Linguistically, this is called clipping. Different parts of different words are omitted or kept. Photograph could not become graph, because that had an existing meaning. Once telephone at least sometimes became phone, television could become telly (or tv), but not vision.
