Since the i-umlaut of /ɑ̃:/ is /e:/ and unstressed short high vowels were lost after a heavy syllable, the expected outcome would have been *sēm- (sometimes *sem-; see below). Two developments interfered. First, lack of i-umlaut shows that the final *-i was replaced with *-a in this prefix, perhaps by analogy with its synonym *halba- (later ). Second, the root vowel shows shortening, since without i-umlaut the regular outcome of /ɑ̃:/ is /o:/.

In most compounds of sam- this shortening is expected, since a prehistoric sound change shortened long vowels before (1) clusters of three consonants, (2) two consonants plus two syllables, or (3) geminates. This shortening could have been eliminated by analogy in many cases (there is no way to know how often, as Old English manuscripts do not normally mark vowel length), but it was apparently maintained in sam-.
