Words showing increased frequency in 2024. (A) Frequencies in 2024 and frequency ratios (r). Both axes are on a log scale. Only a subset of points are labeled for visual clarity. the dashed line shows the threshold defining excess words (see text). Words with r > 90 are shown at r = 90. excess words were manually annotated into content words (blue) and style words (orange). (B) the same but with frequency gap (δ) as the vertical axis. Words with δ > 0.05 are shown at δ = 0.05. Credit: Science Ad...
