Input an English word or the beginning letters of it. Use British orthography. Searches are not case-sensitive.
By clicking the "Perform Search" button, you will search for headwords that have (or begin with) the search expression you have input in their English definition. These headwords are called "Lexemes" in TLS.
If more than one Lexeme is found, you will be shown a hitlist. By clicking the arrow to the left of a Lexeme on the hitlist, you will be taken the detail page of the Lexeme in question. If only one Lexeme is found, you will be shown the detail page right away.
The search is performed in the Lexeme Definition field of the Lexemes file. Please note that this field is not shown in the hitlist, only on the detail page. In order to find more search options and full explanations of the contents of the Lexemes file, select the "Lexemes" file in the "Select File" menu.
