My best guess is that you had the following snippet in .zshrc that
you'd copied from zshwiki.org:

    typeset -gA abbreviations=(
      'sclient' 'openssl s_client'
    )

    magic-abbrev-expand() {
        emulate -L zsh -o extended_glob
        local MATCH
        LBUFFER="${LBUFFER%%(#m)[_a-zA-Z0-9]#}"
        LBUFFER+="${abbreviations[$MATCH]:-$MATCH}"
        zle self-insert
    }

    no-magic-abbrev-expand() {
        LBUFFER+=' '
    }

    zle -N magic-abbrev-expand
    zle -N no-magic-abbrev-expand
    bindkey ' ' magic-abbrev-expand
    bindkey '^x ' no-magic-abbrev-expand
