Append / Prepend

My apologies if this has been discussed before.

Where are you guys seeing append/prepend usage? So far I've interpreted and translated the Swedish version in the context of "attaching" a prefix/suffix to something:

then append - bifoga suffix (English: attach suffix)

then prepand - bifoga prefix (English: attach prefix)
http://www.geni.com/tr8n/phrases/view?translation_key_id=229377

Now, with the new clean forms:

append : http://www.geni.com/tr8n/phrases/view?translation_key_id=230041
prepand : http://www.geni.com/tr8n/phrases/view?translation_key_id=230040

… there is a bit of a dilemma since any direct, short, elegant, counterpart—apart from prefixing/suffixing—is not available in Swedish and since I'm a bit unsure about the actual Geni usage on this, someone enlighten me please!

To clarify, My interpretation is:

append = "suffixed, suffix something to this piece of data"
prepand = "prefixed, prefix something to this piece of data"

So, when translating, I would simply go:

append = suffix
prepand = prefix

Would I be wrong?

PS: is the spelling "prepand" that is used on Geni accepted? I see a lot of "prepend" out there though, is there a difference?

If you are not Language Manager you can not create this logic.
You can look Estonian ones (maybe it will help) -

Suffix is used for names: Sen, Jun., 3rd, 2nd, etc.
There is now (in discussions) request to use also Prefix (field, currently missing) for names: Dr., Sir, Her Majesty, etc.

Roger that & thanks Lauri. I guess I'll roll with the Estonian mode on this, seems workable and straightforward enough imho.
