Portuguese is an example of this - there was a deliberate narrowing of the lexicon in the 20th century, even extending to losing certain tenses like the future perfect, and this has resulted in a narrowing of the field of expression.
For example, in English you can say “by next week, I will have finished the work”, but in Portuguese you boil it down to the simple perfect, and it becomes unclear as to whether you have already done the work or not.
You also just literally can’t translate stuff like “she must have been going to go” or “she would have had to have gone” or “I will have been living here for five years in two weeks”.
This results in a loss of temporal thinking, hypothetical chains, and allocations of causality and responsibility, and while I don’t at all wish to besmirch the good Portuguese people, the results are a real and long-lasting impact on things like economic productivity and the ability to forward plan.
Or maybe it’s just a hangover from Salazar and I’m barking up the wrong tree, but often when I’ve attempted clarification on this stuff the distinction has just not been comprehensible to my interlocutor. I try to use stuff like the future perfect (as it still theoretically exists, but is almost entirely disused) and people just do not understand - either the structure or the concept.
