Spring day with Easter's first card (5)
I believe the answer is:
spade
'card' is the definition.
(the spades are a playing card suit)
'spring day with easter's first' is the wordplay.
'spring' becomes 'spa' (spa can mean a mineral spring).
'day' becomes 'd' (abbreviation for day).
'with' means one lot of letters go next to another.
'easter's first' becomes 'e' (1st letter of 'easter').
'spa'+'d'+'e'='SPADE'
(Other definitions for spade that I've seen before
include

"Digging implement"
,
"Gardening tool (maybe so called)"
,
"10
