Dex is a nickname for?

[name_m]Decimus[/name_m]? [name_u]Dexter[/name_u]? [name_m]Declan[/name_m]?

The husband and I love the nickname [name_m]Dex[/name_m]…(or at least think we do this week…)
Does it work with all of the above? Which would be best?
We arr leaning towards [name_m]Decimus[/name_m] or [name_m]Declan[/name_m]…
Other names you can you [name_m]Dex[/name_m] with?

(We also thought of using [name_m]Alexander[/name_m] as a middle name…and then using a name that began with D as a first…since [name_m]Alexander[/name_m] is a family name anyway… would that work? (You can get [name_u]Lex[/name_u] from [name_m]Alexander[/name_m]…and say we used [name_m]David[/name_m] [name_m]Alexander[/name_m] “[name_m]Dex[/name_m]”?)
Thoughts? Suggestions? Comments?

It works with [name_u]Dexter[/name_u] and [name_m]Declan[/name_m], but I’ve only heard [name_m]Decimus[/name_m] pronounced with a soft C, so it doesn’t apply.

[name_m]Dex[/name_m] could be short for [name_m]Derek[/name_m].

Your middle name idea works.

I like the idea of [name_m]David[/name_m] [name_m]Alexander[/name_m] nn [name_m]Dex[/name_m].

Some other names that might work…

[name_m]Deccan[/name_m]
[name_m]Mordechai[/name_m]
[name_m]Zedechiah[/name_m]
[name_m]Benedek[/name_m]

I think it works for [name_u]Dexter[/name_u], [name_m]Declan[/name_m], and D___ [name_m]Alexander[/name_m]. [name_m]Dex[/name_m] is a cool nickname!

I think all of your [name_m]Dex[/name_m]- or Dec- suggestions work.
But my favorite by far is [name_m]David[/name_m] [name_m]Alexander[/name_m]. I think it is a classic and very handsome name.

[name_f]Love[/name_f] the suggestion of [name_m]Zedechiah[/name_m]… which is actually already on our list…except we prefer [name_m]Zedekiah[/name_m].

[name_m]Dex[/name_m] is a cool nickname for [name_m]Declan[/name_m]! I actually love [name_m]Declan[/name_m] but I’m not wild about Dec, so this is a good alternative, I love it!

[name_m]David[/name_m] [name_m]Alexander[/name_m] with the NN [name_m]Dex[/name_m] could work well to! I can’t think of anymore though so I’m not much help, but I love all of your options!

You can call him [name_m]Dex[/name_m] regardless of which of the D names you chose, the one that is the most instinctive though in my opinion is [name_u]Dexter[/name_u].
