Some hypotheses have been advanced with a stronger basis: It is possible to recognize the suffix -isma in some of the oldest forms which represents an evolution of the Gallic suffix -isama (usually a superlative mark) which is found in the name of the Gallic divinity Belisama and very common in toponymy in toponymic types such as Blesme, Bellême, etc. including changes in the final -esme, -ême which is similar to Angoulême.Xavier Delamarre also cited Uxisama "very high" giving Exmes, Huismes, etc. and *Lētisamā "very grey" giving Louesme (Côte-d'Or, Leesma in 1101), Lesme (Saône-et-loire)Xavier Delamarre, Dictionary of the Gallic language, éditions Errance, Paris, 2001, p. 199,329, .

The identification of the primitive form Eculisna then alternating the old forms -isna and -isma led Ernest Nègre to prefer the first with -isna. The first element would be Ecul-. According to him, we can neither affirm the Celticity of these two elements nor their meaning. The alteration in *Angulisma was caused by the attraction of the Germanic personal name Angelisma whose existence was confirmed by Marie-Thérèse Morlet. Iculisma / Ecolisma would consist of a Gallic radical eco meaning "water", followed by the suffix -lisima meaning "relates to". Iculisma would be "well-watered".Jean-Marie Cassagne and Stéphane Seguin, Origin of names of towns and villages of Charente, Jean-Michel Bordessoules, 1998, 311 pages, p. 15 and 16, Xavier Delamarre analysed the element Eco- to come from Equoranda (or Egoranda) as the origin of many names in France and considers that the element ico / equo- was not Celtic.
