False. Old English was a synthetic language, which means that words' endings signalled grammatical order and word order was rather free. As Old English differentiated words' categories through their endings, words could be placed anywhere in a sentence and readers would know the category of the words.
Whenever you read about Latin's influence on Old English, you will find its influence on Old English vocabulary. As scribes translated Latin works into Old English, they frequently found no translation for some Latin words and, thus, they introduced new Latin ones.
