of Common Romanian. During this stage, the speakers of particular dialects started to borrow terms from the neighboring Slavic peoples. Ukrainian, Polish and Russian influenced the 13th century Daco-Romanian dialects of Moldavia and Maramureș; Serbian loanwords appeared in the Daco-Romanian variants of Banat and Crișana; Bulgarian influenced the Wallachian dialects of Daco-Romanian; Istro-Romanian was exposed to a strong Croatian influence for centuries; while Aromanian and Megleno-Romanian were strongly influenced by Bulgarian and Macedonian. Some older studies, like that of linguist Alexandru Cihac, considered two-fifth of the Romanian lexis of Slavic origin. Recent studies determined that about 16.5% of the nouns, 14% of the verbs (most of which have the fourth conjugation form), 11.8% of the adjectives, 20% of the adverbs and 1.6% of the function words were borrowed from Slavic languages. The ratio of Slavic loanwords is especially high in the religious vocabulary (25%) and in the semantic field of social and political relations (22.5%). Slavic loanwords make up more than 10% of the Romanian terms related to speech and language, to basic actions and technology, to time, to the physical world, to possession and to motion. Some loanwords were used to name new objects or concepts. For instance, Slavic loanwords in the Romanian vocabulary of agriculture show either the adoption of the Slavs' advanced agricultural technology by the Romanians, or the transformation of their way of life from mobile pastoralism to a sedentary agriculture. Other loanwords replaced inherited Latin terms. For instance, it is unlikely that the Romanian ancestors had no term for love even if a iubi ("to love") is a Slavic loanword. In some cases, certain dialects retained inherited Latin term which were replaced by Slavic loanwords in standard Romanian. For example, the inherited Latin term for snow (nea) is only used regionally or in poems, while standard Romanian prefers zăpadă and omăt which were borrowed from Slavic languages. Most Slavic loanwords are connected to situations which stir up emotions, including dragă ("dear") and slab ("weak"). According to Robert A. Hall, originally Slavic-speaking individuals spread these emotive terms, because they continued to use them even when they were talking in Romanian. Schulte notes that "in antonym pairs with one element borrowed from Slavic, there is an intriguing tendency for the Slavic word to be the one with more positive connotation". For instance, Slavic a iubi ("to love") against inherited a urî ("to hate"), and Slavic prieten ("friend")
