The affix aṇ comes after a root hūñ 'to call' veñ 'to weave', māṅ 'to measure', when the object is in composition with it.,
This debars the affix क 3.2.3; as स्वर्गे + ह्वे + अण् = स्वर्गे + ह्वा + अ = स्वर्गे + ह्वाय + अ 7.3.33 = स्वर्गह्वायः (the य is added by rule 7.3.33, 'when a krit affix with an indicatory ण or म follows', the augment य is added after the verbs that end in long आ). So also तन्तुवायः, धान्यमायः ।,
