    "abstract": "A child’s first word is an important step towards language. Aggregated\nacross children, the distribution of these first productive\nuses of language can act as a window into early cognitive\nand linguistic development. We investigate both the variability\nand predictability in children’s first words across four\nnew datasets. We find, first, that children’s first words tend to\nemerge earlier than previously estimated: more than 75 percent\nof children produce their first word before their first birthday.\nSecond, we find a high degree of consistency in the types of\nthings children name in their first words, independent of the\nage at which they are produced. Finally, we show that the particular\nwords that children produce first are predictable from\ntwo linguistic factors: input frequency and phonological complexity.\nTogether, our results suggest a degree of independence\nbetween early conceptual and linguistic development",
