The phonetical characteristics of Insubric language are the halving of consonants, the voicing of intervocalic consonants, the transformation of Latin "u" into Insubric /y/, Latin short "o" into /œ/ø/, partial transformation of long "o" into /u/, the falling of final vowels except "a", loss of Latin suffix "re" of infinitive, suffix "i" for 1st person, partial falling of intervocalic "d", partial transformation of "a" into "o" when followed by "l" and another consonant, the transformation of Latin groups "pl", "bl", "fl", "gl" into "pi", "bi", "fi", "gi" (read: dj) and of group "ct" into "c" (read: tsh), the nasalization of vowels followed by "n" or its transformation into a velar nasal, the falling of final "l" and "r" when followed by a long vowel, the distinction of vowel length, the partial transformation of intervocalic "l" into "r".
An uncommon feature for a Romance language is the extended use of idiomatic phrasal verbs (verb-particle constructions) much in the same way as in English.
Unlike most Romance languages, Western Lombard has vowel quantity oppositions.
Examples are: Like the Italian language, when a proclitic pronoun is used, however, this comes before the verb and the auxiliary: The singular third person of the verb is preceded by a proclitic word ("el" for masculine subject, "la" for feminine subject: identical to definite articles) that remind the subject; the singular second person of the verb is preceded by a proclitic word ("te").
Unlike Italian, whenever this happens the subject pronoun must not be dropped: The Insubric definite article derives from a Latin distal demonstrative, ille.
For example: Besides, definite article is used in front of proper nouns: Western Lombard is a synthetic fusional language.
The indefinite article takes the following forms: Most of the masculine nouns and adjectives terminate without suffix.
Alike other Latin languages, a plural noun that refers to both males and females is masculine.
Unlike other Romance languages, in Western Lombard it does exist the negative form of the imperative.
Insubric has four conjugations: Unlike other Neo-Latin languages, Lombard language presents a characteristic probably inherited from the prolonged past contact – Sprachbund – with Germanic languages and dialects such as Allemannic, this is the presence of Phrasal Verbs / Compound (linguistics): An adjective can be made into a modal adverb by adding -ment (analogous to the English "-ly") to the ending of the feminine singular form of the adjective.
E.g.: Adjectives ending in -r or -l simply add -ment: In other cases, a periphrasis is used instead: There are also some cases of adverbs that are typically Insubric: Adverbial phrase are really common in Western Lombard: Western Lombard prepositions link two related parts of a sentence.
