Tearing up come rashly? (10)

I believe the answer is:

lachrymose

I'm a little stuck... Click here to teach me more about this clue!

'tearing' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?

'up come rashly?' is the wordplay.
'up' indicates an anagram (letters get chucked up).
'come'+'rashly'='comerashly'
'comerashly' with letters rearranged gives 'LACHRYMOSE'.

Can you help me to learn more?

(Other definitions for lachrymose that I've seen before include "In bits" , "showing sorrow" , "Tearful (literary)" , "Sad" , "This is given to crying" .)

I've seen this clue in The Telegraph.
