Bogin points out that Kollmann had intended the meaning to be "retaining youth", but had evidently confused the Greek teínein with the Latin tenere, which had the meaning he wanted, "to retain", so that the new word would mean "the retaining of youth (into adulthood)".
Bogin sinala que Kollmann pretendía que tivese o significado de "reter a xuventude", pero que, evidentemente, confundiu o termo grego teínein co latino tenere, que tiña o significado que el quería, "reter, manter", para que a nova palabra significase "a retención da xuventude (na idade adulta)".
