It is the absence of this articulator node in the borrowing language which causes the problem and, consequently, the deletion of \h\ in loanwords.
The experiments discussed in this paper bear on the question of loanword adaptation from a slightly different perspective.
I do not mean to imply that reanalysis or the adaptation of loanwords are uninteresting to the morphophonologist.
Intervening factors, such as analogy, orthography, etc. in loanword adaptation, cannot be completely controlled.
Historically the natural tendency has been for loanwords to change to conform to the new linguistic system in which they are used.
The loanwords were not pronounced by the interviewers.
Though informal, this test further indicates that phonetic variants have little impact on the phonological adaptation of loanwords.
Addressing and disconfirming some predictions of phonetic approximation for loanword adaptation.
