DESCRIPTION:Based on EF-Cambridge Open Language Database\, the study ident
 ifies\nsecond language (L2) developmental patterns of English grammatical\
 nmorphemes and investigates the effects of learners' native language (L1)\
 nand proficiency on the patterns. Through the process\, it addresses the\n
 extent to which individual variation is observed in the development.\nTarg
 eting 140\,000 essays written by 46\,700 learners of 10 L1 backgrounds\nac
 ross a wide range of proficiency levels\, the study found that the\ndevelo
 pmental patterns of accuracy (i) can be clustered into a few\ngroups\, (ii
 ) are similar across morphemes\, (iii) are affected by\nlearners' L1 backg
 rounds and proficiency\, and (iv) are nonlinear. Large\nindividual variati
 on was observed in the absolute accuracy\, the accuracy\norder\, and the d
 evelopmental trajectories of the morphemes. Together\,\nthey point towards
  a complex\, dynamic\, and nonlinear nature of morpheme\ndevelopment.
