It sometimes happens that a question comes up with very poor wording to the point that readers cannot really understand what the asker is actually asking.
I focused on this: "The animals which have flowing blood if killed or wounded. But I need to make a noun phrase using Adj+noun". (See link below.)
To mean: The animals that have blood leaving their body if killed or wounded.
As a result, my answer contains a series of verbs that could describe that blood leaving the body....And, along with verbs, I provided adjective + noun phrases such as: spurting blood.
One comment under my answer said the OP wanted an adjective + noun and ould not
This is a case in point: bloody or having flowing blood
Having read the question many times, I came to the conclusion that it is about asking how blood exits the body when it is injured. The body of an animal or person.
It would seem, moreover, that the OP did not want to clarify the question.
So, some posters found various synonyms for bloody, such as sanguineous. And although an injured body can be bloody, the word bloody is not used to describe how blood leaves the body. Bloody as a descriptive word means covered in blood.
In cases like this, it would seem to me that downvoting what is a perfectly good answer is not great.
What can be done to encourage OP's to clarify confusing questions.
