Alright, I know that this is where you see many writers and poets here on NL, so I brought this here.
And this is for those who may not have known this before...we learn everyday.

That said, the word I'm talking about is:

WRITE-UP.

Do you see how I wrote it? Yea, the appropriate ways to write that word is either WRITE-UP (that is with an unspaced hyphen in between the 2 words that make up the compound word), or WRITE UP (with the 2 words spaced but no hyphen in between). However, the 1st one ("WRITE-UP" ) is the uppermost, most appropriate and probably best used/most commonly used, but the 2nd ("WRITE UP" ) is also allowed.
I always see people write the word wrongly, viz: "WRITEUP", including even in serials (mags and newspapers) and this is obviously misleading many people including innocent learners. Well, "WRITEUP" is wrong, though spellings of both the 2 right ones and the 1 wrong one are the same.

Now you know.
If you thank me for telling you this...
I'll simply smile
