Appendix:Latin and Romance style guide

The following are not hard rules so much as recommendations born of years of experience—and suffering.

Where to stop
It is advised to stop as soon as the etymology reaches the first Latin lemma. There is no need to go back further to Proto-Italic or beyond. If one wishes to categorize Romance words by their longer-range relationships, one can always use dercat. In the future, it should be possible to have this automated anyway.

Nouns
Most Romance nouns correspond best to the accusative form of their Latin ancestors. Latin nouns are, however, lemmatized in their nominative forms. In most cases the difference is fairly trivial and not worth worrying about. The, can be said straightforwardly to derive from ,  (nominative forms).

There are cases, however, when the Latin nominative and accusative differ in some important way- for instance in the presence or absence of certain consonants or even an entire syllable (which may affect the stress position). In such cases it is advised to link to the Latin nominative lemma whilst displaying the accusative form which gave rise to the Romance descendant. For instance, the etymology for reads '', which links to the Latin nominative lemma.

Verbs
Most Romance verbs are lemmatized in the infinitive, while Latin verbs are lemmatized in the 1SG present indicative form. The approach suggested above for verbs works just as well here. For instance, the etymology for reads '', which links to the Latin lemma.

Semantics
If a Romance word has more or less the same sense as its Latin antecedent, which is usually the case, then there is no need to gloss the latter.

Cognates
There is no need to list random cognates in a Romance etymology. One or two may be provided when they are in some way rare, interesting, or genuinely useful to have on-hand. Some examples are:
 * Citing on the entry for  to provide a familiar point of reference for a lesser-known language.
 * Citing on the entry for, both to shore up the latter's validity and to provide an idea of what the Mozarabic vowels would have been.
 * Cross-linking and, as these represent the only branches of Romance to inherit.

Alternative forms
If the Romance words derive from an alternative form of the Latin lemma, it is recommended to list them as descendants under that lemma with a label such as 'reflexes of the variant X'. See monachus#Descendants or impleo#Descendants for examples.

Reconstructed forms
It is advised to list reconstructed Vulgar Latin forms in the descendants section of Latin entries rather than among the derived terms, where they are liable to be lost in a sea of regular Latin derivatives. Placing them in the descendants section has the additional benefit of allowing the use of desctree or see desc.
