You always ask such good questions! I really love answering them :)
1 -- Rose ~ I love this name on it's own, not as a nickname for anything. It has so much class and elegance and beauty about it, that it's completely substantial on it's own. If it *had* to be short for something, I suppose I would choose the longer name "Rosalie", which I also like, but I like the sound of the full name as well and would probably just call her Rosalie and not Rose.
2 -- Kate ~ I adore this name, it means "pure" which is very sweet. I like it as a middle name by itself, but if I were to use it as a first name, I would use it as a nickname for Katherine - which I also love and it's my cousin's name as well so I would consider using Katherine or Kate in honour of her. I have Grace Katherine on my list and Isabella Kate; I love it as a first name as well though.
3 -- Addie ~ I adore the name Adeline (add-uh-LINE) and though I prefer the full name on it's own, if I were to use a nickname for it, I would use Addie. So, Adeline "Addie" :)
4 -- Ali ~ I love this nickname and this spelling the most (it looks the sweetest and it's the simplest which is usually what I go for in names!), I love Alison and if I were to use Alison as a name, I would, without doubt, use Ali as a nickname. Alison "Ali" (though I could see many full names with the potential nickname "Ali" - Adeline, like I said in 3, could have Ali as a nickname too...)
5 -- Elle ~ love El(le), it's beautiful :) there are many longer names that I love with this nickname, my top ones would be Elizabeth, Eloise and Eleni. If I were to choose just one of the names, I would choose Elizabeth, though Eleni used to be on my favourites list, I like Elizabeth "Elle" slightly more.
6 -- Anna ~ Anna is a sweet name, but I like it as a full name on it's own usually (I like the pronunciation AH-nuh better than ANN-uh though), however if I were to use it as a nickname, I would choose the full name, Anastasia (though I also like Annalise and Anya). I do prefer, however, Annie as a nickname for all of them.
7 -- Emma ~ I like Emma as a name on it's own and that is entirely how I view it, Emma is my best friend's name and I call her Emmy (I'm really the only one that does though, otherwise she just goes by Emma or Em) - so if I were to use Emmy, I would have it as a nickname for either Emma or Emily.
8 -- Viv ~ I adore this as a nickname for Vivienne (which is a favourite name of mine and is on my list as a middle name for Rose), it's simple and sweet and it looks nice written down, I do love Vivienne as a full name though as well.
9 -- Lily ~ I have a couple of names that I like with Lily as a nickname. Lillian, Liliana and Lilia are just some of the really nice ones (I recently heard Lillium and I quite like it to though I'm not sure I'd be brave enough to use it). If I had to choose one, I would choose Lilia, I just love the way it sounds and it's less common than Lillian. I definitely prefer the spelling Lily over Lilly as well.
10 -- Evie ~ I don't like this name, honestly, it's just unattractive sounding to me. If I were to use it as a nickname, though, I would use the full name Genevieve or Geneva (probably Genevieve). I adore the name Geneveive, but I probably would use the nickname Genna before I considered Ev(i)e, because like I said, I'm not a fan.
