Questions & Answers about Ten nowy bezprzewodowy alarm jest bezgłośny.
How are the adjectives bezprzewodowy and bezgłośny formed in this sentence?
Both use the prefix bez- (meaning without) attached to a noun root, capped with an adjective suffix. Bezprzewodowy comes from przewód (wire or cable) plus the suffix -owy. Bezgłośny comes from głos (voice or sound) plus the suffix -ny.
Why does the root vowel change from ó in the noun przewód to o in bezprzewodowy?
Why is there an ś in bezgłośny instead of the s found in the root noun głos?
Adding the suffix -ny usually triggers a consonant mutation, softening the preceding consonant. Here, the hard s from głos softens to ś before the n. This palatalization is a very common pattern when turning nouns into adjectives.
Why is the adjective bezgłośny in the nominative case after jest? Shouldn't it be instrumental?
