Leptorhine is an adjective and
lepto- is a combining form. You can't really say "Like a horny sightless woman on a blind date, she begins to knead her heavy friendship-ring-laden fingers into my face. 'Leptorrhine ... kumquat-headed ...'" or "... friendship-ring-laden fingers into my face. 'Lepto nose ... kumquat-headed ...'"
As for instances of ATM without the
machine or PIN without the
number, sure you'll run into those in the wild. They don't make
ATM machine or
PIN number wrong even if context makes it clear what you're talking about without the
machine or
number. Even with context there can be confusion.
Teller at the bank, helping a confused customer with his ATM card: "Do you have your PIN?"
Customer: "Yes ma'am. Rat cheer in mah pocket. It's a BIC."
