Misused: Ill Girl

Ill Girl is a trope describing a character who is debilitatingly ill. Important distinguishing factors are that the character is often a young and innocent child, the ill girl remains cute, despite her illness, and that her illness sends another character(s) off on a mission to cure her or at least ease her suffering.
A Wick Check determined that the trope suffered misuse under a variety of categories, including simply "an ill character”, with only eight checked examples determined as correct usage (9.5%). Both Related.IllGirl and Related.IllBoy were checked due to their large number of wicks, though there are also redirects for Ill Child (31) and Ill Man (16). To summarize the findings found here:

• 8/84 Correct Usage or 9.5%
• 6/84 Only Debilitatingly Ill or 7%
• 17/84 Just sick/weak or 20%
• 5/84 Character is Mentally Ill or 6%
• 12/84 Has a disability or 14%
• 15/84 Other Misuse or 18%
• 4/84 Unclear or 4.75%
• 17/84 ZCE or 20%

Combining the various misuse categories, this trope has a 90% misuse rate. The laconic isn’t the worst description in the world, summarized as "Someone, usually female, who’s debilitatingly sick." but I think it is probably one of the reasons for some misuse. A common theme in misuse is describing a character who was sick in the past or before the work takes place, often as a freebie in addition to Sickly Child Grew Up Strong. Tightening the restrictions and/or making them clearer may help alleviate future misuse.
I know renaming is usually a last resort, but I also believe the trope name itself is a source of misuse. It is a cutesy, close rhyme title, but it may be too broad, especially with the trend of swapping out "girl" for the appropriate descriptor (i.e. "boy", "man", "woman"), which doesn't necessarily violate the How to Write an Example rule on not altering trope titles in example lists (gender is an exception) but still not great because of the short trope title, so it'll still affect alphabetization.
