I have to say that I don't particularly agree that we say more with fewer words. I just got through talking to my grown daughter about being the mother of grown kids, and I found that what took me more than a minute or so to say (several words) felt very effective to me. I just felt like it my choice of several words made good, loving, mother/daughter communication.
However, even though I think it does take more than three words to effectively say something loving, I'll go with:
"You are treasured." That, though, doesn't specify that I'm the one who treasures the other person; and if I say, "I treasure you," that somehow seems to put more emphasize on me than on the other person. And, it doesn't even, to me, come across as loving as "you are treasured". I suppose I see having "the gift of words" for communicating as also having the gift of being able to use several of them to communicate/express love as precisely and effectively as something like love deserves to be expressed. (My point here isn't to argue the OP's point, by any means. I just thought throwing in some thoughts about using words to express love seemed kind of right here.)
I understand you ;-) I already saw my wording was a bit clumsy. I really wanted to say, sometimes we say more with fewer words. And sometimes we speak many words and say nothing. I thank you for all your words :-)
