They are not very common, but still there are some English words that contain two Vs in a row. Unlike two Us in a row which are present only in borrowed words (usually from Latin), two Vs are generally used in proper English words to modify the sound of the preceding vowel; for example “savy” (a non-existing word) would be pronounced say-vee, whereas “savvy” is pronounced sæv-ee. Here are all such words:
