Understanding 付け忘れんな(ぁ)


This is from a subs2srs anki deck that I'm studying.

(Edit: [Audio on soundcloud](https://soundcloud.com/magnus-lidbom/clip_01) )

The original transcription and translation is:

> 付け忘れんな # Don't forget to record it.

But it sounds to me like:

> 付け忘れんなぁ{hllhh} or maybe 付け忘れんなぁ{hhlhh}

My ability to hear pitch accents is not great, so I tried to confirm it with
VoceVista. Top is start of clip. Right side is higher pitch. The first blue
line is the start of the れ syllable. The second is the start of the な. The
third is the end of the clip. [![Audio pitch

I've read [Is the word 「やんな」positive or
negative?](https://japanese.stackexchange.com/questions/33097/is-the-
word-%e3%82%84%e3%82%93%e3%81%aa-positive-or-negative) but the pitch accents,
if I'm getting them right, don't seem to match, and the long なぁ is also
different. Again, assuming I'm hearing and understanding that right, which is
not certain.

So what is going on here?

Taking a stab in the dark, I'm guessing that the ん functions as a contraction
of るな, which seems consistent with the falling pitch, and then the なぁ is the
confirmation seeking version of the な particle that is sometimes pronounced
long.

I can't find anything online to confirm this intuition though...




It's not a direct answer, but it is a problem on "intonation", the changes in
pitch not affecting meaning of words unlike the accent.

Despite the discussion on the godan verb やる, つけ忘れんな is always negative as it
is ichidan verb. やるな{LHL} and やりな{LHH} can be realized as やんな{LHL} and
やんな{LHH} keeping their accent and number of morae. However, つけ{LH}忘れな{HHH}
(verb つけ忘れる in 連用形 + perticle な) and つけ{LH}忘れるな{HHLL} (verb つけ忘れる in 終止形 +
perticle な) have different number of morae, and only the latter can be
realized つけ忘れんな in colloquial speech. The accent is still つけ{LH}忘れんな{HHLL}.

As another possibility, just based on the text つけ忘れんな, it can be seen as the
combination of verb つけ忘れる in 未然形 + aux verb ぬ (negation) in 終止形 + particle な
(emotionality), because the auxiliary verb ぬ is often realized as ん. Also in
this case, the accent is つけ{LH}忘れんな{HHLL}. (Yet this sounds like monolog and
not likely here.)

What I want to say here is that な is gramatically still a particle of
prohibition, but its length and pitch are affected by the intonation and other
elements.
