It is to give a meaning or a semantic form to something that in principle uses another type of language, or that lacks it. The written or spoken word semanitizes a fact, an object; but also in art or design you can modify a text so that your drawing reinforces the meaning or modify it, or change the pronunciation or accentuation of a voice so that it evokes another with different meaning (in this case it would be rather 'remantizing').
