Am I right to think that the next sentence has a duality in meaning?
I got here early so that we could have a few minutes along together. (M. Swan, Practical English Usage, §583.7)
Could we tell without context whether this that-clause is the purpose or the consequence of the main clause, 'I got here early'? By any chance, could the 'got' imply something? Or is there any word usually added to mean either purpose or consequence, and so the sentence is no ambiguous to native speakers?
Thank you. :)
