DESCRIPTION:The development of the early vocabulary is a central question
  when investigating language acquisition. As pointed out by previous res
 earch\, semantic and phonological neighbourhood density play an importan
 t role when determining which words are acquired first. Effects were fou
 nd to be larger than those caused by well-studied psycholinguistic varia
 bles such as word length.\nHowever\, there is an ongoing disagreement ab
 out the role of overlapping neighbourhoods: Is a target word with many n
 eighbours that are similar in sound and meaning learnt earlier? For a hi
 ghly normative sample of school children and college students\, Cassani 
 and Limacher\, 2022 found earlier acquisition for those systematic words
  supposing a preferential acquisition scenario of vocabulary growth. Nei
 ghbourhoods were computed in relation to all the words in the input a ch
 ild receives (EXT-like growth).\nI challenge their results by employing 
 a new calculation method for word systematicity introduced by Stich et a
 l.\, 2026. The method is based on a preferential attachment scenario for
  vocabulary growth (INT-like growth): Systematicity values are computed 
 in relation to all other words known by the child. An impeding effect on
  word acquisition was revealed for longitudinal\nCDI data of Norwegian-s
 peaking children between 18 and 36 months old.\nWhen including an intera
 ction of word systematicity and word frequency in my statistical analysi
 s\, no significant effect was detected which I argue is due to the small
  size of the child-directed speech corpus I used.\n\nCassani\, G.\, & Li
