Lavaan model

Dear R-users,
Does somebody know what does the "Estimate" reported by the Lavaan model
tell us?
I assume this tells the relative strength of the dyadic relations.

The 'Estimate' column contains the estimated model parameters. There are 
many different kinds of model parameters. Under the heading 'Latent 
variables', you may have factor loadings. Under the heading 
'Regressions' you may have regression coefficients. Other parameters are 
(residual) variances and (residual) covariances.
