When you "give leeway" to someone, you are allowing them some freedom or flexibility in their actions or decisions. Some synonyms for "give leeway" include "give some wiggle room", "provide some latitude", "allow for some maneuverability", "offer room for negotiation", "grant some concessions", "be more lenient", "give some breathing space", "afford some flexibility", "tolerate some deviation" and "permit some deviation". All of these alternatives communicate a similar message to provide some allowance or space for someone to operate within, rather than imposing strict restrictions or rules. It's important to give leeway in appropriate circumstances, to promote creativity, innovation, and problem-solving.
