Register: keep up versus uphold
Along the colored chips, register rises from everyday to formal. Keep up sounds spoken: keep up the good work. Keep is plain and works almost everywhere. Look after is warm and personal, often for gardens, pets and homes. Sustain suits effort, growth and long periods. Uphold is the stiffest choice and pairs with laws, decisions, values and reputations.
Courts uphold rulings; nobody upholds a lawn. Matching register to object is half of the job.
