-овый or -о́вый • (-ovyj or -óvyj)

1. used to form adjectives from nouns, often relational

   ‎пла́стик (plástik, “plastic”) + ‎-овый (-ovyj) → ‎пла́стиковый (plástikovyj, “plastic”)

   ‎ба́за (báza, “base”) + ‎-овый (-ovyj) → ‎ба́зовый (bázovyj, “base, basic”)

   ‎сосна́ (sosná, “pine”) + ‎-о́вый (-óvyj) → ‎сосно́вый (sosnóvyj, “pine”) (relational)

   ‎кулачо́к (kulačók, “cam”) + ‎-о́вый (-óvyj) → ‎кулачко́вый (kulačkóvyj, “cam”) (relational)

The suffix is added to the stem (i.e. without final vowels, as in ба́з- and сосн- above, and without epenthetic vowels, as in кулачк- above). The stress of the base form is preserved. If the stress of the base is on a lost vowel, it is transferred to the suffix.
