[name_m]Hi[/name_m],
This is my friends name, short for [name_f]Eleanor[/name_f] which she never uses. I think Ellies cute for kids but I can’t really see it aging well on teens, adults or old people.
WDYT?

[name_f]Ellie[/name_f] actually ages beautifully. Until recently, I had trouble imagining it on a [name_m]YOUNG[/name_m] person lol. Too much “Miss [name_f]Ellie[/name_f]” as I was growing up, I guess. I prefer [name_f]Ellie[/name_f] as short for another name, usually it’s [name_f]Eleanor[/name_f] or [name_f]Elizabeth[/name_f], but my favorite longer name for the [name_f]Ellie[/name_f] nickname is [name_f]Elena[/name_f].
[name_f]Ellie[/name_f], [name_f]Elle[/name_f], [name_f]Ella[/name_f] are all very popular given names and nicknames right now. I think they are all darling. I even gave my daughter an “ella” name, though she goes by the nn [name_f]Lu[/name_f]. I honestly think [name_f]Ellie[/name_f] works on any age.
By themselves I find them very overdone and prefer them as nicknames (longer names to help differentiate in case she’s one of however many in whatever setting). [name_f]Eleanor[/name_f] is gorgeous though! If I was an [name_f]Eleanor[/name_f] I’d be [name_f]Eleanor[/name_f] or [name_f]Noor[/name_f].
I agree with @gabriela. I think [name_f]Ellie[/name_f] ages well, and I sometimes have a hard time seeing it on a child! I think [name_f]Ellie[/name_f] is a great name.
[name_u]Love[/name_u] [name_f]Ellie[/name_f]!
We are stuck between naming our girl [name_f]Caroline[/name_f] or [name_f]Eleanor[/name_f] ([name_f]Ellie[/name_f]). My husband doesn’t think [name_f]Ellie[/name_f] will sound good when she’s 30. It’s nice to hear others think differently about the nickname [name_f]Ellie[/name_f]. 
I’d pick [name_f]Eleanor[/name_f] nn [name_f]Ellie[/name_f] in a heartbeat. It’s a gorgeous name and so versatile. Besides the fact that [name_f]Ellie[/name_f] ages well, if she doesn’t like it, she can go by any number of other nicknames.
My cousin is an [name_f]Eleanor[/name_f] who goes by [name_f]Ellie[/name_f]. I called her [name_f]Eleanor[/name_f] growing up and she only really adapted [name_f]Ellie[/name_f] once in high school (as far as I know), and I only see her once or twice a year, so I always forget to call her by her nickname.
Anyway, I think it ages wonderfully. I prefer it to [name_f]Eleanor[/name_f] and it’s a sweet name that can easily standalone.
I love [name_f]Ellie[/name_f] as a nickname and I think it (a) ages well and (b) can perfectly standalone. However, I personally prefer it as a nickname for something longer, my favourite being [name_f]Eleanor[/name_f].
[name_f]Eleanor[/name_f] has long been a popular name in the UK and [name_f]Ellie[/name_f] is a totally normal name for adults and teenagers.
I love [name_f]Ellie[/name_f]! I also thought it might not age well, but I suppose she could always choose to go by [name_f]Eleanor[/name_f] in the professional world.
I adore [name_f]Ellie[/name_f]! I also love [name_f]Eleanor[/name_f] though.
I have a gorgeous [name_f]Ellie[/name_f]. We adored just [name_f]Ellie[/name_f] but only liked the “full versions.” So we went with what we loved and adored. We are so happy we did! She’s only nine, but she has not had any problems with it.
See, I think [name_f]Ellie[/name_f] ages just fine. All the [name_f]Ellie[/name_f]'s I’ve met besides my daughter were great aunts, or grandmas.
[name_f]Ellie[/name_f] is my boyfriend’s favorite name, so I have a bit of a soft spot for it. I would only use it as a nickname though.
I love [name_f]Ellie[/name_f]. It’s got the style of [name_u]Allie[/name_u], but seems fresher and friendlier. I think it’s a perfect nn for [name_f]Eleanor[/name_f], a name also close to my heart as it was my grandmother’s name.
The only think I don’t like is how popular [name_f]Ellie[/name_f] is becoming. There will probably be several Ellies in her school.
Make sure to check how popular it is in your area, don’t go off of just the general popularity. My [name_f]Ellie[/name_f] is nine years old and we have yet to met another [name_f]Ellie[/name_f] as a full name or as a nickname under the age of fifty. She’s the only [name_f]Ellie[/name_f] in her class, and the school that I know of. I volunteer in her class, front office, and school events/sports. Also, I have a 19 month old in daycare and have not met another there.
I’m not all that fond of [name_f]Ellie[/name_f], to be honest. If I were you I would just choose [name_f]Ellen[/name_f] / [name_f]Eleanor[/name_f] / [name_f]Elizabeth[/name_f] / [name_f]Elaine[/name_f] or something as her full name, and then see what comes naturally as a diminutive.
My name is [name_f]Ellie[/name_f], short for [name_f]Elinor[/name_f]. I am 22. I’ve gotten so many compliments on my name and I’ve grown to really love it.
I believe that [name_f]Ellie[/name_f] is so timeless and fresh, it could honestly work on any age. However, I am partial to [name_f]Ellie[/name_f] on a teenager. Something about the (nick)name sounds really spunky and free-spirited – perfect for a daring and feisty youth.
I am so incredibly tired and bored of hearing ‘[name_f]Ellie[/name_f]’. I hear that name/nickname EVERYWHERE and it’s always some little girl so I can’t picture it on anyone older.
I adore [name_f]Eleanor[/name_f], but I would prefer [name_f]Nora[/name_f], [name_f]Noor[/name_f] or [name_f]Elle[/name_f] as a nickname. [name_m]Just[/name_m]. Not. [name_f]Ellie[/name_f].
