Place ekki (not) immediately after the finite verb:
• Ég sé ekki sjúkrahúsið.
Use geta (to be able) plus the supine form séð of sjá:
• Ég get séð sjúkrahúsið. (I am able to see the hospital)
• Ég get ekki séð sjúkrahúsið. (I cannot see the hospital)
The strong‐verb past of sjá is sá, so you say:
• Ég sá sjúkrahúsið.
Use the 3rd‐person singular form of sjá, which is sér, and the pronoun hann (he):
• Hann sér sjúkrahúsið.
• sj is the voiceless alveolo-palatal fricative [ɕ], somewhat like English sh but with the blade of the tongue raised toward the palate.
• The final ð is a voiced dental fricative [ð], similar to the th in English this, though a bit softer.
