Gratias Stan,

pro tu patientia con me!
Mi additional recerca in dictionarios (vide p. e. Webster's sur le rete,
al basso) vermente appoia tu interpretation!
  Me resta comprender _proque_ io _senti_ como si fomentar serea un plus
forte action que simplemente applicar calor??!
  Esque il ha un resimilantia con le anglese "FOAM"?  Forsan...
Mais io es nunc convincite haber alicubi retro in mi cerebro
subconscientemente confundite  fomentar e FERMENTAR !!!

Pardono!!!

Sigmund
