Today Merriam-Webster, America’s best known keeper of words, announced new entries for their collegiate dictionary in 2014. Among them are telling specimens like selfie, hashtag and steampunk, reflecting lasting cultural obsessions that have become widespread enough to earn a place in the big red book.

“So many of these new words show the impact of online connectivity to our lives and livelihoods,” says Editor-at-Large Peter Sokolowski, in a press release. And that’s not all.

Many of the 150 new words do indeed speak to some intersection of pop culture and technology, like Auto-Tune and paywall. But others, like freegan and turducken, remind us how many modern Americans are bravely pursuing alternative eating habits, refusing to forego dumpsters as a regular food source or to consume merely one kind of poultry at a time. And though MW does not say as much, others remind us of what lasting influence Kate Middleton has in our society (See: baby bump, fangirl).

Here is a selection of the new words, with their definitions and the earliest year Merriam-Webster editors could find them being used:
