I don't understand the usage of "à enchaîner" here.
Can someone explain the grammar ? It's not a fixed expression as far as I can see. Why à + infinitive ? Why not en + present participle ? Is it the same thing ? How would we translate this ? By/while enchaining ?
Is it the same as "en enchaînant" (en + present participle) , which would mean "in enchaining", or perhaps "while enchaining"
am I correct ?
