Did Wagner call his recurring themes 'leitmotifs', who did, and what did he call them?

In Ellis's English translations, Wagner's own accounts (1851 'A Communication to My Friends'; 1879 'On the Application of Music to the Drama') describe a 'tissue' or 'web' of 'thematic Motivs', 'root-themes' and 'chief-moods'; the only place the word Leitmotive appears in the volumes inspected is in the 1879 essay, in quotation marks, attributed to his younger friend Hans von Wolzogen ('what he calls my Leitmotive'). Ellis's Vol. II translator's preface also uses a word the OCR renders 'leitmotivtn' (read as leitmotiv-) as a metaphor for recurring words, not for music. Within these texts, the term is therefore Wolzogen's name for the phenomenon that Wagner himself describes differently. Whether Wolzogen first coined the word, or someone else, was not established. Curator qualifications: Full count of 'leit' (case-insensitive) in the OCR: 2 - line 8583 (essay text) and line 17684 (index entry '"Leitmotive," 184.'). Lines 8581-8585: 'one of my younger friends * who has viewed the characteristics of what he calls my " Leitmotive " rather in the light of their dramatic significance'. Line 8612: '* Freiherr Hans von Wolzogen. — Tr,'. Joined text: 'this Unity consists in a tissue of root-themes pervading all the drama'.
