I'll start with 'they say...' phrase structure in English.
At first it was very strange for me. Who are 'they'? Why we don't mention them before?
Reason is: my native languge has complex system of postfixes and prefixes.
This has a penalty: statistically every phrase is longer 10-30% than in English.
But on the other hand prefixes and suffixes effectively bind role of the words in the sentence and there is high potential for free words order. Changing order of words in sentence can shift stresses on particular word, but not change overall meaning.
But also omitting of words is highly exploited.
So, we say 'Say[suffix meaning plural subjects + present continuous] ...'. Without noun, but with suffix binding, this phrase automatically becomes something like '(Some people not important here) say ....' or mentally 'Process of saying by multiple people is in progress and they say ...'.
So it was interesting to meet strict English word ordering.
Maybe you have something fun or intreresting to share too.
