I've searched these two words in the Longman, Merriam Webster and also in the Cambridge Dictionary (on line version) and the only one which shows the word "touristic" is Merriam Webster. I've also searched it on the internet and realized that some other ESL students have the same doubt about it. Do native English speakers ever use this "touristic" or only foreigners?
I would not class that as a standard English word. I haven’t ever seen it before (in over 50 years of being a native English speaker) so I would say it’s a fair bet that it’s used by foreigners only.
I would understand it to mean ‘related to tourism’.
"touristic’ is recognized as an adjective by Oxford Dictionary, as is ‘historic’.
It means ‘typical of tourists or tourism’.
You visit Paris, and what do you buy? A miniature Eiffel Tower, displayed, no doubt, among a vast collection of other touristic ‘objet d’art’ for sale to tourists!
(For objet d’art, read ‘kitsch’)
A report by the European Commission, no less, includes the sentence:
[color=indigo]“Its principal aim is to enable these groups to carry out their own evaluation of touristic potential, taking into account supply, demand, competition and market trends. This will also enable them to decide on the particular territory in which the tourism development project will be implemented.”
touristic potential: having, or not, those things that the tourist is interested in.
The question was not ‘is it found in any dictionaries?’ but ‘Is it used?’
It has a brief mention (under ‘tourist’ 3. hence #IC) in my print version of the Oxford dictionary too, but in my experience, it isn’t generally used.
The example you quote doesn’t use it either!
Edit:
I see you have added a second example now.
The European Commission - largely comprising non-native English speakersm eh?
Anyway, I’ve made my point. I don’t think it’s generally used.
I’m happy to add to your cheery mood, even though you are mistaken. I rarely make negative comments, though some of my honest comments could be misread as such - and in this instance the only ‘negativity’ displayed is toward the European Commission clowns.
