Verbs are consensually recognised at the level of category.
The major problem concerns the different internal organisations of the verbal systems which characterise Romance languages, on the one hand, as opposed to English, on the other hand. Romance languages, but also, e.g. German, are highly inflectional, whilst English presents very few inflections and scarce morphological distinctions for moods and tenses.
Furthermore, the Leech & Wilson and MULTILEX proposals, in particular, introduce new distinctions which, in the present proposal, appear distributed on different levels.
