When to sign "I Love You" using the version with "I","L" & "Y" vs "I" + "Love" + "You"

[Benn]

Sorry if the title was confusing, I'm taking an ASL 1 class at my high school and we have learned how to sign "I Love You" using the signs "I" + "Love" + "You" and the abbreviated version using "I" "L" and "Y" on one hand. I was wondering whether or not there was a difference in the significance between the two and when to use either one. Sorry if this was the wrong place to post this! I'm very new to the forum.

This is the perfect place to post this!  In my experience, the ILY handshape version is more friendly and succinct, good for goodbyes to friends or lovers(works for groups too).  The  I, Love, You version is more emotive, and can be used more emphatically.  I would use it for emphasis or if you're trying to make a stronger point(body movement and facial expression are vital).  Hope this helps!

I have been told by local interpreters and Deaf that to sign the ILY single hand shape is very casual.  Used more with friends and people that you love, but it is not really used for romantic love unless it's something like a casual goodbye to a partner.  I LOVE YOU signed individually is used for romantic love.  Something you would say for emphasis with a partner. 

Also, many younger Deaf will not sign LOVE in regards to objects.  Older Deaf will still use this version, but younger tend to go with KISSFIST when referring to things/objects/activities that they Love.
