it could be both.
In native Hindi, the masculine and feminine word would both be written and pronounced differently, but this distinction is often lost in English transliteration.
The masculine name is pronounced with a 'silent' 'a', written in the IPA as /ə/. For simplification purposes it might be also written and pronounced as 'Shiv' (शिव)
The feminine name is pronounced with a more pronounced 'a' sound, written in the IPA as /aː/. For simplification purposes it might also be written and pronounced as 'Shivaa' or Shivā (शिवा)
Shiva is a sanskrit word which means PURE. It is the name of Lord Shiva (also known as Rudra) It also means THE AUSPICIOUS ONE. This is how you write Shiva in Sanskrit - शिव (Sanskrit is an ancient sacred Hindu Language)
Edit:
Shiva is defined as Sham mangalam karoti iti Shiva. Shiva is the one who brings auspiciousness (mangalam or mangal). Shiva also means kalyaaNakaarii atman or Brahman as Adi Shankara says in Atma ShaTakam and as said in Guru Gita that there is no difference between Shiva and Guru Tatva.
Shiva is also connected with or represents 3 powers or shakti
Icchaa shakti, vidya shakti and kriya shakti
