words we don't have in English

I've been noticing the word renowned all over the place, since I posted about its use.

I wondered if there's a word in English to describe the way we start to take notice of a phrase or object once we get sensitised to it. I feel there is a term for this experience, but I can't think of it. Perhaps I've seen it in a psychology book.

Being an inquisitive person, I looked around the Internet trying to find such a word. I had no success. But I did come across a great site with lists of words from other languages that we might wish we had in English.

I loved most of them, but one will certainly have to enter my vocabulary right now. The Scottish word tartle describes:

  The act of hestitating while introducing someone because you’ve forgotten their name. 

A further search finds lots of references to this word, but the only authoritative one I could find was the Collins Dictionary,  where someone has submitted it for consideration as a new word. It is marked 'under consideration'.

I've taken ages to write this post because I've been roaming around the Net looking at lists of great words we should have. Here's another list I particularly like.
