Abstract
The limiting shape of the random Young diagrams associated with an inhomogeneous random word is identified as a multidimensional Brownian functional. This functional is identical in law to the spectrum of a Gaussian random matrix. Since the length of the top row of the Young diagrams is also the length of the longest (weakly) increasing subsequence of the random word, the corresponding limiting law follows. The Poissonized word problem is also briefly studied, and the asymptotic behavior of the shape analyzed.
