[xikano]

The word nothing has seven alphabetical letters composed of two vocals and five consonants.

N= voiced nasal alveolar
O= back half closed rounded vowel
T= voiceless alveolar stop
H= voiceless fricative glottal
I= front half closed rounded vowel
N= voiced nasal alveolar
G= voiced velar stop

3 voiced and 2 voiceless
1 voiced stop
1 voiceless stop
2 nasals
3 alveolar
1 velar
1 glottal
1 fricative

Sounds which are produced with complete closure are referred to as stops.

Glottal is a constriction of complete closure between the vocal folds.

Fricative: Friction is created as the air escapes.

Alveolar nasal stops entail complete closure between the blade of the tongue and the alveolar ridge, voicing and escape of the air.

A voiced velar stop is a stricture of complete closure.

What can be deduced out of this knowledge?

The word nothing, phonetically speaking, lets in and lets out air via the constriction of the tongue. In fact, when you say the word nothing, first you draw in air and then you let it out.

What does all this mean? Nothing. Except perhaps that there is a lot of closure going on there ....
