Usage note

Likely in the senses “probably destined” and “probably” is often preceded by a qualifying word like very, more, or quite: The board is very likely to turn down the request. The new system will quite likely increase profits. However, despite statements to the contrary in some usage guides, likely in these senses is standard without such a qualifier in all varieties of English: It will likely be a bitter debate. The shipment will likely arrive on Thursday. See also apt, liable.
