One way I use to learn Latin vocabulary is to seek for derived Spanish/English words which meaning I know. For instance, gressus derived into egresar and ingresar, Spanish words which mean to exit ("e[x] gressus") and to enter ("in gressus"), respectively.
In this spirit, when I face a new Latin word, oftentimes I want to find Spanish/English derivatives, but I lack a systematic tool to do this. Wiktionary does offer this for some words but it is very far from systematic. The entry for gressus, for example, lacks this.
Are you aware of any tool, dictionary or website that offers this information in a systematic way?
