Hint
Another example, PEN is a complete word because:
-en = ten
p-n = pin
pe- = pea
Answer
Three of the words are not complete: flew, rook, lamp.
Reasoning
The remaining 7 words can be changed as follows:
team:
-eam = beam
t-am = tram
te-m = term
tea- = tear
cost:
-ost = host
c-st = cast
co-t = coat
cos- = cosy
flew:
-lew = blew
f-ew = ---- X
fl-w = flow
fle- = flex
ward:
-ard = card
w-rd = word
wa-d = wand
war- = warm
fail:
-ail = nail
f-il = foil
fa-l = fall
fai- = fair
rook:
-ook = book
r-ok = ---- X
ro-k = rock
roo- = roof
soft:
-oft = loft
s-ft = sift
so-t = sort
sof- = sofa
most:
-ost = cost
m-st = mast
mo-t = moat
mos- = moss
lamp:
-amp = damp
l-mp = lump
la-p = ---- X
lam- = lamb
Note that LARP is an uppercase acronym, and not in any of my word lists.
load:
-oad = road
l-ad = lead
lo-d = loud
loa- = loaf
